JP 2005-252853 A
However, the RFID antenna having the structure as shown in Patent Document 1 has a problem that the antenna size increases because three different antennas need to be arranged on the same substrate. In addition, when a plurality of antennas are arranged close to each other and wireless communication is performed using one antenna, there is a problem that communication is disturbed due to the influence of the remaining antennas and communication becomes unstable.
SUMMARY OF THE INVENTION An object of the present invention is to provide a wireless IC device that can use RF signals of a plurality of frequency bands for an RFID tag and that is small in size and excellent in radiation characteristics.

With this configuration, power reception and communication can be performed using RF signals of a plurality of frequency bands for the RFID tag, and highly efficient communication is possible.
(2) The first wireless IC and the second wireless IC are configured, for example, in the same package.
Thereby, the mounting cost can be reduced.
(3) The first frequency band is lower than the second frequency band, the radiation electrode has a resonance frequency higher than the first frequency, and the magnetic field radiation electrode is an RF signal in the first frequency band. Including a magnetic field radiating electrode portion.
With this configuration, the magnetic field radiation electrode acts as a magnetic field antenna in the first frequency band, and acts as an electric field antenna in the second frequency band, so that there is no deterioration in radiation characteristics due to interference between antennas. An excellent wireless IC device can be configured.
(4) The magnetic field radiation electrode unit serves both for receiving the RF signal in the first frequency band and for transmitting and receiving the RF signal in the second frequency band.
With this configuration, it is not necessary to separately provide the antenna for the RFID tag of the first frequency and the antenna for the RFID tag of the second frequency, so that the entire size can be reduced.
(5) The resonance frequency of the radiation electrode portion is lower than the second frequency band.
With this configuration, the radiation electrode can act as a single radiation electrode equivalent to the frequency for the second RFID tag, and the radiation characteristics of the RFID tag are enhanced.
(6) The radiation electrode includes a line electrode and a capacitor electrode that forms a capacitance between both ends of the line electrode.
With this configuration, the resonance frequency per occupied area of the first RFID tag radiation electrode can be lowered by the lumped constant of the inductance L of the line electrode portion and the capacitance C of the capacitance electrode portion. Conversely, the occupied area per predetermined resonance frequency can be reduced. As a result, the overall size can be reduced. In addition, when the frequency for the second RFID tag is 10 times or more higher than the frequency for the first RFID tag, the capacitive electrode portion has a very small impedance at the frequency for the second RFID tag, so the entire radiation electrode Acts as a single radiation electrode spread in a plane at the frequency for the second RFID tag, and the radiation characteristics as the second RFID tag can be further improved.
(7) The capacitor electrode includes a first electrode and another electrode facing each other in the thickness direction through a dielectric layer, and the line electrode has a spiral-shaped portion that circulates around the capacitor electrode. The one-side electrode is electrically connected to the inner peripheral end of the line electrode forming the shape portion, and the cross-line electrode is provided to connect between the outer peripheral end of the line electrode forming the spiral-shaped portion and the other side electrode.
With this configuration, the impedance of the crossing line electrode portion is reduced at the frequency for the second RFID tag, and the crossing line electrode portion is equivalently integrally connected in spite of the line electrode portion having a spiral shape. It can be regarded as a radiation electrode with high radiation efficiency.
(8) The line electrode has an electrode removal portion, the first wireless IC is mounted so as to be coupled to both ends of the line electrode of the electrode removal portion, and the outer peripheral end side of the line electrode of the crossing line electrode The second wireless IC is mounted so as to be coupled in the vicinity.
With this configuration, the crossed electrode portion and the capacitive electrode portion have very small impedance at the frequency for RFID, and the effect as the radiation electrode of the entire radiation electrode is enhanced, and the radiation characteristics of the RFID tag antenna can be improved.
(9) A pair of the radiation electrodes is provided, and the first and second wireless ICs are electrically connected or electromagnetically coupled to each of the pair of the radiation electrodes.
With this configuration, the pair of radiation electrodes can act as two first RFID tag radiation antennas having different frequencies. For example, the radiation electrode can be used as an RFID tag having a different frequency in the HF band. In addition, by mounting a radio IC for the second RFID tag so that a pair of radiation electrodes are connected as a dipole antenna, it can function as a radiation electrode for a relatively large area of the RFID tag, thus realizing excellent radiation characteristics. it can.
(10) The radiation electrode further includes an electric field radiation electrode part which forms an equivalent dipole antenna together with the magnetic field radiation electrode part in a pair with the magnetic field radiation electrode part, and the second wireless IC includes the magnetic field radiation electrode part.

With this configuration, high radiation characteristics can be obtained.
(11) The capacitor electrode is arranged inside the line electrode forming the spiral shape portion, and the field emission electrode portion is arranged outside the line electrode forming the spiral shape.
With this configuration, since the radiation electrode is not shielded by the spiral line electrode portion, high radiation characteristics can be maintained.
(12) The first or second wireless IC is a wireless IC chip that is electrically connected to the radiation electrode.
With this configuration, the wireless IC portion can be made extremely small, and the overall size and thickness can be reduced.
(13) The first or second wireless IC includes a power supply circuit board including a matching circuit including at least one inductor, and a wireless IC chip mounted on an upper surface of the power supply circuit board and conducting to the matching circuit.

Thereby, the reception of the RF signal in the first frequency band and the transmission / reception of the RF signal in the second frequency band are not necessarily simultaneous. That is, power reception and communication can be performed at different timings. For this reason, the reader / writer using the first frequency band and the reader / writer using the second frequency band can be provided independently.
(15) The wireless IC device includes, for example, a sensor, and the first wireless IC or the second wireless IC includes means for transmitting a detection result by the sensor.
With this configuration, sensor information can also be transmitted and received.
According to the present invention, power reception and communication can be performed using RF signals of a plurality of frequency bands for RFID tags, and highly efficient communication is possible. Also, the radiation electrode acts as a radiation electrode at the first and second RFID frequencies, and it is necessary to provide an antenna for the RFID tag of the first frequency and an antenna for the RFID tag of the second frequency separately. Since there is no, it can be downsized as a whole. In addition, the radiation electrode acts as a magnetic field antenna for the first RFID tag and an electric field antenna for the second RFID tag, and there is no deterioration of the radiation characteristics due to interference between the antennas, so that a wireless IC device having excellent radiation characteristics is configured. it can.

First to fifteenth examples relating to a wireless IC device are shown. Among these examples, the ninth to fifteenth examples are embodiments of the present invention.
FIG. 2 is a diagram illustrating a configuration of the wireless IC device according to the first example . FIG. 2A is a plan view thereof, and FIG. 2B is a cross-sectional view of the ab portion in FIG. FIG. 3 is a diagram showing an electrode pattern on the base material 21 and its operation. The wireless IC device 101 is formed by forming predetermined various electrodes on a base material 21 and mounting an RFID tag wireless IC 31 and an RFID tag wireless IC 51 made of an IC chip.
In FIG. 2, a wireless IC device 101 is obtained by forming a desired electrode pattern made of a conductor such as copper or aluminum on a base material 21 made of a resin film such as PET or PP. Specifically, a copper foil or an aluminum foil is used to pattern a copper foil or an aluminum foil by etching.
As shown in FIG. 2, a spiral-shaped line electrode portion 22 and one side electrode 23 connected to the inner peripheral end thereof are formed on the upper surface of the base material 21. On the lower surface (back surface) of the base material 21, the other side electrode 24 is formed at a position facing the one side electrode 23, and the other side electrode 24 and the position facing the outer peripheral end of the line electrode portion 22 (front and back connection portion) The crossing line electrode 25 which crosses the line electrode part 22 in the middle of the circuit and bridge-connects is formed.
The end portion of the crossing line electrode 25 and the outer peripheral end of the line electrode portion 22 are electrically connected by a front / back connection portion 26.
The first RFID tag wireless IC 51 is mounted in the middle of the line electrode portion 22 so as to be inserted.
Further, a linear field emission electrode portion 33 is further formed on the upper surface of the base material 21. The second RFID tag wireless IC 31 is mounted so that the terminal electrodes are connected to the vicinity of one end of the field emission electrode portion 33 and the front and back connection portion 26, respectively.
The wireless IC device 101 illustrated in FIG. 2 functions as an RFID tag in a first frequency band (for example, an HF band of 13.56 MHz) and an RFID tag in a second frequency band (for example, a UHF band of 900 MHz band). The operation as an HF band RFID tag is as follows.
The line electrode portion 22 functions as a loop (spiral) magnetic field radiation electrode in a portion from the outer peripheral end to the inner peripheral end of the spiral shape, and acts as an inductor, The other electrode 24 acts as a capacitor. The magnetic field radiation electrode portion 20 is configured by the line electrode portion 22, the electrodes 23 and 24 of the capacitive electrode portion, and the crossing line electrode 25. The inductor L and the capacitor C of the magnetic field radiation electrode unit 20 constitute an LC resonance circuit. This resonance frequency is set higher than the frequency for the first RFID tag. Therefore, the magnetic field radiation electrode unit 20 is used on the lower frequency side than the resonance frequency, that is, operates in an induction type (magnetic field type), and acts as a magnetic field radiation electrode at the frequency for the first RFID tag. .
FIG. 3A shows a state before the first RFID tag wireless IC 51 and the second RFID tag wireless IC 31 are mounted. In FIG. 3A, a portion B is a mounting portion of the first RFID tag wireless IC 51, and the first RFID tag wireless IC 51 is mounted on the electrode removal portion of the line electrode portion 22.
The first RFID tag wireless IC 51 operates using a voltage generated between both ends of the electrode removal portion of the line electrode portion 22 as a power source, and simultaneously changes the impedance connected between both ends of the electrode removal portion of the line electrode portion 22 ( By responding to a question from the reader / writer.
Since the second RFID tag wireless IC 31 and the field emission electrode portion 33 exist outside the closed circuit of the LC resonance circuit, they do not affect the first RFID tag.
Next, the operation as the second RFID tag will be described with reference to FIG.
FIG. 3A shows a state before the second RFID tag wireless IC 31 and the first RFID tag wireless IC 51 are mounted. A capacitance is generated between the intersecting line electrode 25 and the line electrode portion 22 that intersects with the substrate 21 (A portion), but the impedance due to the capacitance is very low in the second frequency band. Similarly, the capacitance between the one-side electrode 23 and the other-side electrode 24 is very low in the RFID frequency band. Furthermore, the impedance of the portion B can be lowered if the distance between the end portions is made as narrow as several hundred μm. Therefore, in the frequency band of the RFID tag (for example, 900 MHz which is the UHF band), the line electrode part 22, the electrodes 23 and 24 of the capacitive electrode part, and the crossing line electrode 25 are continuously radiated as shown in FIG. Acts as an electrode (field emission electrode) 20.
The resonance frequency of one continuous radiation electrode 20 is lower than the second frequency band. Therefore, this one continuous radiation electrode 20 acts as a field radiation electrode in the second frequency band. Then, one continuous radiation electrode 20 and the field radiation electrode portion 33 act as a dipole antenna.
The field emission electrode portion 33 has a length substantially equal to a quarter wavelength in the second frequency band. Similarly, the line length of one continuous radiation electrode 20 corresponds to a quarter wavelength in the second frequency band. However, the length and size of the electric field radiation electrode portion 33 and the one continuous radiation electrode 20 are not limited to the ¼ wavelength, but as a radiation electrode in the second frequency band, particularly as a radiation electrode of a dipole antenna. Any size can be used.
When the first frequency band and the second frequency band are compared, it is desirable that the second frequency band has a relationship that is ten times higher than the first frequency band. With such a frequency relationship, when the wireless IC device 101 operates as the second RFID tag, the capacities of the A part and the B part shown in FIG. 3B are about several pF, and are several in the UHF band. It becomes a low impedance of about 10Ω and acts as a single electrode as shown in FIG. 3C, and the characteristic is a directivity close to that of a dipole antenna.
With the configuration described above, the radiation electrode for the first and second RFID tags can be made one. Further, since the distance between the first RFID tag radiation electrode and the second RFID tag radiation electrode is not required, the area can be reduced. Furthermore, since there is no equivalent of, for example, an HF band RFID tag that has been blocked to prevent radiation of, for example, a UHF band RFID tag, a decrease in gain can be eliminated.
In addition, the one side electrode 23 of the capacitive electrode portion and the other side electrode 24 of the capacitive electrode portion are not limited to the structure facing each other with the base material 21 interposed therebetween, and the one side electrode and the other side electrode are disposed on one surface of the base material. And a dielectric layer may be formed between the one side electrode and the other side electrode.
FIG. 4 is a plan view of the wireless IC device according to the second example . In the example shown in FIG. 2, the linear field emission electrode portion 33 is formed along one side of the spiral line electrode portion 22 and one side of the base material 21, but in the example shown in FIG. 4, the field emission electrode portion 33 is formed. The shape of is different from that. In the wireless IC device 102 </ b> A of FIG. 4A, the field emission electrode portion 33 a is folded so as to reciprocate along one side of the line electrode portion 22 and one side of the base material 21.
In the wireless IC device 102B of FIG. 4B, the field emission electrode portion 33b is formed linearly along the one side of the substrate 21 and away from the magnetic field emission electrode portion 20.
Furthermore, in the wireless IC device 102 </ b> C of FIG. 4C, the field emission electrode portion 33 c is formed in an L shape along the two sides of the base material 21.
The configuration and operation other than those described above with reference to FIG. 4 are the same as those in the first example .
In the structure shown in FIG. 4A, an equivalent line length (electric length) of the field emission electrode portion 33a can be obtained without substantially increasing the area of the base material 21, and a necessary frequency of the RFID tag can be obtained. The area of the base material 21 required for this can be reduced accordingly.
In the structure of FIG. 4B, since the magnetic field radiation electrode portion 20 and the field radiation electrode portion 33b extend away from each other, the radiation efficiency as a dipole antenna is increased. Therefore, the sensitivity of the RFID tag can be increased.
In the structure shown in FIG. 4C, the field emission electrode portion 33c having a required line length (electric length) can be formed by effectively using the area of the base material 21, so that the sensitivity as an RFID tag can be improved. The overall size can be reduced while increasing.
5 is a plan view of the wireless IC device according to the third example , FIG. 6 is a cross-sectional view of the first RFID tag electromagnetic coupling module 50 used in the wireless IC device 104, and FIG. 7 is used in the wireless IC device 103. It is sectional drawing of the electromagnetic coupling module 30 for the 2nd RFID tag.
The first RFID tag electromagnetic coupling module 50 includes a feeder circuit board 52 and a wireless IC chip 54 mounted on the feeder circuit board 52. The second RFID tag electromagnetic coupling module 30 includes a power supply circuit board 32 and a wireless IC chip 34 mounted thereon. In the first and second examples , the two connection terminals formed on the wireless IC 51 are directly connected to the electrode removal part of the magnetic field radiation electrode part 20, but in the example shown in FIG. On the other hand, the first RFID tag electromagnetic coupling module 50 is electromagnetically coupled. In the first and second examples , the two connection terminals formed on the wireless IC 31 are directly connected to the magnetic field radiation electrode unit 20 and the electric field radiation electrode unit 33, respectively. In the example shown in FIG. The second RFID tag electromagnetic coupling module 30 is electromagnetically coupled to the radiation electrode section 20 and the field radiation electrode section 33.
As shown in FIG. 6, capacitor electrodes 14c and 14d and inductor conductors 13c, 13d, and 13e are formed inside the feeder circuit board 52, respectively. Electrode pads to which the inductor conductors 13c and 13d are respectively connected are formed on the upper surface of the power supply circuit board 52, and the solder bumps 6c and 6d of the wireless IC chip 54 are joined to the electrode pads, respectively.
The wireless IC chip 54 includes a circuit that supplies power to the solder bumps 6c and 6d. The inductor conductors 13c, 13d, and 13e constitute a matching circuit, and the capacitor electrodes 14c and 14d and the end of the line electrode portion 22 are capacitively coupled to each other. In this way, impedance matching is performed between the wireless IC chip 54 and the loop antenna, and capacitive coupling is performed with a capacitance of about several pF. As a result, the characteristic change caused by the displacement of the mounting position of the wireless IC can be eliminated, and the antenna efficiency can be increased by improving the matching with the radiation electrode. In addition, since the matching circuit performs matching at the frequency used in the first RFID tag, a broad band can be achieved without being affected by the resonance frequency of the magnetic field radiation electrode unit 20 alone.
As shown in FIG. 7, capacitor electrodes 14aa, 14ab, 14ba, 14bb and inductor conductors 13a, 13b are formed inside the power supply circuit board 32, respectively. Electrode pads to which the capacitor electrodes 14aa and 14ba are connected are formed on the upper surface of the power supply circuit board 32, and the solder bumps 6a and 6b of the wireless IC chip 34 are joined to the electrode pads, respectively.
The wireless IC chip 34 includes a circuit that supplies power to the solder bump 6a and a circuit that supplies power to 6b. Therefore, a matching circuit is configured by the LC circuit of the capacitor between the capacitor electrodes 14aa and 14ab and the inductor by the inductor conductor 13a. The inductor conductors 13a and 13b are magnetically coupled to the front / back connection part 26 and the field emission electrode part 33, respectively. In this way, impedance matching is performed between the wireless IC chip 34 and the dipole antenna, and electromagnetic coupling is performed. As a result, the characteristic change caused by the displacement of the mounting position of the wireless IC can be eliminated, and the antenna efficiency can be increased by improving the matching with the radiation electrode. In addition, since the matching circuit performs matching at the frequency used in the second RFID tag, the bandwidth can be increased without being affected by the resonance frequency of the antenna by the magnetic field radiation electrode section 20 and the field radiation electrode section 33.
When operating as the first RFID tag (HF band RFID tag), the capacitance of several pF between the second RFID tag electromagnetic coupling module 30 and the front / back connection portion 26 has a high impedance of about 10 kΩ. Therefore, the second RFID tag electromagnetic coupling module 30 and the field emission electrode portion 33 hardly affect the resonance frequency of the first RFID tag (HF band RFID tag).
On the other hand, when operating as the second RFID tag (UHF band RFID tag), the second RFID tag electromagnetic coupling module 30 has a capacitance of several pF between the front and back connection portion 26 and the field emission electrode portion 33 and the second The matching circuit inside the RFID tag electromagnetic coupling module 30 is designed so that impedance matching between the wireless IC chip 34, the magnetic field radiation electrode unit 20, and the electric field radiation electrode unit 33 can be achieved.
Note that, in the LC circuit on the feeder circuit board 32, the frequency of signals transmitted and received by the magnetic field radiation electrode unit 20 and the field radiation electrode unit 33 can be substantially determined.
By using the electromagnetic coupling modules 30 and 50 in this way, it is not necessary to set the length of the radiation electrode, the electrode interval, etc. according to the frequency, the shape of the radiation electrode can be variously changed, and the design of radiation characteristics is free. The degree is improved. In addition, since the feeder circuit board may be mounted at a position where it can be electromagnetically coupled to the radiation electrode, the mounting accuracy can be relaxed.
FIG. 8 is a plan view of a wireless IC device according to a fourth example . The wireless IC device 104 according to the fourth example includes two magnetic field radiation electrode portions 20a and 20b.
On the upper surface of the substrate 21, two spiral line electrode portions 22a and 22b and one side electrodes 23a and 23b connected to the inner peripheral ends thereof are formed, respectively. Further, the other side electrodes 24a and 24b are respectively formed on the lower surface of the base material 21 at positions facing the one side electrodes 23a and 23b, and a line is provided between the other side electrodes 24a and 24b and the front and back connection portions 26a and 26b. Crossing line electrodes 25a and 25b that cross-connect the electrode portions and are bridge-connected are formed. The front and back connection portions 26a and 26b electrically connect the ends of the crossing line electrodes 25a and 25b and the outer peripheral ends of the line electrode portions 22a and 22b, respectively.
A first RFID tag electromagnetic coupling module or wireless IC chip 50a, 50b is mounted in the middle of the line electrode portions 22a, 22b, respectively.
The magnetic field radiating electrode portion 20a including the line electrode portion 22a, the electrodes 23a and 24a, and the crossing line electrode 25a acts as a resonance circuit for the first RFID tag, and the line electrode portion 22b, the electrodes 23b and 24b, and the crossing line electrode The magnetic field radiation electrode portion 20b composed of 25b functions as another resonance circuit for the first RFID tag.
Further, the second RFID tag electromagnetic coupling module 30 is mounted so that the connection terminals are connected to the front and back connection portions 26a and 26b, respectively.
The two magnetic field radiating electrode portions 20a and 20b function as field radiating electrodes in the second frequency band in the second frequency band, as in the above-described embodiments, and their length and size are as follows. Since it corresponds to almost ¼ wavelength in the second frequency band, a structure in which a dipole antenna is connected to the wireless IC 31 is obtained.
This structure can be used as two HF band RFID tags having different frequencies.
In addition, according to such a structure, the symmetry of the two magnetic field radiation electrode portions 20a and 20b is good, so that the radiation characteristic as the second RFID tag is further improved.
FIG. 9 is a plan view of the wireless IC device 105 according to the fifth example . In this example, the line electrode lead-out portion 28 is pulled out from the middle of the line electrode portion 22 so that the impedance of the mounting portion of the electromagnetic coupling module 30 is inductive (L property). That is, as viewed from the mounting part of the electromagnetic coupling module 30, a loop is formed by a part of the line electrode part 22 and the line electrode lead part 28, so that the impedance is not capacitive but inductive. Become.
FIG. 10 is a partial plan view of a wireless IC device according to a sixth example . In any of the first to fifth examples , the sheet-like base material is configured to be used by sticking it to an article or the like, but the wireless IC device 106 according to the sixth example is For example, it is configured on a mounting board of a terminal device (mobile phone) of a mobile communication system.
In FIG. 10, a non-ground region 42 where the ground electrode 41 is not formed is provided at the end of the mounting substrate 40, and the spiral line electrode portion 22 and one continuous from the inner peripheral end are formed on the upper surface of the non-ground region 42. A side electrode 23 is formed. On the lower surface (back surface) of the non-ground region 42, the other side electrode 24 is formed at a position facing the one side electrode 23, and the other side electrode 24 and a position facing the outer peripheral end of the line electrode portion 22 (front and back connection portion) The crossing line electrode 25 which crosses the line electrode part 22 in the middle of the circuit and bridge-connects is formed. The end portion of the crossing line electrode 25 and the outer peripheral end of the line electrode portion 22 are electrically connected by a front / back connection portion 26.
The first RFID tag electromagnetic coupling module 50 is mounted in the middle of the line electrode portion 22 so as to be inserted. The line electrode portion 22 and the electrodes 23 and 24 act as a radiation electrode for the first RFID tag.
The electromagnetic coupling module 30 is mounted so as to be coupled to the front / back connection portion 26 and the ground electrode 41. The magnetic field radiation electrode unit 20 and the ground electrode 41 including the line electrode unit 22, the electrodes 23 and 24, and the crossing line electrode 25 function as a radiation electrode for the second RFID tag. That is, since one terminal electrode of the wireless IC 31 is connected to the magnetic field radiation electrode portion 20 and the other terminal electrode is connected to the ground electrode 41, the whole acts as a monopole antenna.
According to such a structure, it is possible to configure on a mounting substrate such as a mobile phone, and it is not necessary to form another radiation electrode for configuring a dipole antenna, so that the entire occupied area can be reduced.
Note that the wireless IC devices shown as the fourth and fifth examples may be provided on the upper surface of the non-ground region 42 of the mounting substrate.

In each of the first to sixth examples , the capacitive electrode portion is disposed inside the spiral line electrode portion. However, in the example shown in FIG. 10, the capacitive electrode portion is disposed outside the spiral line electrode portion. Is arranged. That is, the spiral line electrode portion 22 and the one-side electrode 23 continuous from the outer peripheral end thereof are formed on the upper surface of the base material 21, and the other-side electrode 24 is formed on the lower surface of the base material 21 at a position facing the one-side electrode 23. And the crossing line electrode 25 extending to a position facing the other side electrode 24 and the inner peripheral end of the line electrode part 22 is formed. The end portion of the crossing line electrode 25 and the inner peripheral end of the line electrode portion 22 are electrically connected to each other. With such a configuration, the magnetic field radiation electrode unit 20 including the line electrode unit 22, the electrodes 23 and 24, and the crossing line electrode 25 functions as a resonance circuit of the first RFID tag.
Further, a field emission electrode portion 33 is formed on the upper surface of the base material 21, and the second RFID tag electromagnetic wave is connected so that the terminal electrode is coupled to the end portion of the field emission electrode portion 33 and the one side electrode 23, respectively. A coupling module 30 is mounted.
According to such a structure, both the capacitance generated at the position where the line electrode portion 22 and the crossing line electrode 25 face each other and the capacitance generated at the position where the electrodes 23 and 24 face each other have a very low impedance in the frequency band of the RFID tag. Therefore, the magnetic field radiation electrode unit 20 can be regarded as one continuous electrode in the frequency band of the RFID tag, and acts as a radiation electrode. Also in this case, since the wireless IC is mounted in the vicinity of the crossing line electrode 25 and the electrodes 23 and 24, the effect as a uniform metal plate radiation electrode is enhanced.
<< Eighth Example >>
FIG. 12 is a plan view of a wireless IC device according to an eighth example . On the upper surface of the base material 21, a magnetic field radiation electrode portion 20 formed in a loop shape and partially in a meander shape is formed. Further, an L-shaped field emission electrode portion 33 is formed on the upper surface of the base material 21.
A first RFID tag electromagnetic coupling module 50 is mounted in the middle of the magnetic field radiation electrode section 20. The second RFID tag electromagnetic coupling module 30 is mounted between the end of the field emission electrode portion 33 and a part of the magnetic field emission electrode portion 20. The magnetic field radiation electrode unit 20 acts as a loop antenna for the first RFID tag. In the second frequency band, the magnetic field radiating electrode portion 20 is equivalent to a uniform metal plate-shaped radiating electrode, so that the magnetic field radiating electrode portion 20 and the electric field radiating electrode portion 33 serve as a dipole antenna for the second RFID tag. Works.
In addition, since the magnetic field radiation electrode unit 20 is configured not to be spiral but to be a closed loop in the same plane, the magnetic field radiation electrode unit 20 can be configured only on one side of the base material 21.
<Ninth example >
FIG. 13A is a plan view of the wireless IC device 109 according to the ninth example . FIG. 13B is a plan view showing a state in which an electrode pattern is formed on the base material 21 which is one of the constituent elements 109 of the wireless IC device. The wireless IC device 109 is obtained by mounting an RFID tag wireless IC 31 made of an IC chip and a first wireless IC chip 61 on a base material 21.
As shown in FIG. 13, a spiral-shaped line electrode portion 22 and one side electrode 23 connected to the inner peripheral end thereof are formed on the upper surface of the base material 21. On the lower surface (back surface) of the base material 21, the other side electrode 24 is formed at a position facing the one side electrode 23, and the other side electrode 24 and the position facing the outer peripheral end of the line electrode portion 22 (front and back connection portion) The crossing line electrode 25 which crosses the line electrode part 22 in the middle of the circuit and bridge-connects is formed.
The first wireless IC chip 61 is mounted in the middle of the line electrode portion 22 so as to be inserted.
The wireless IC device 109 illustrated in FIG. 13 has a function of receiving power of an RF signal in a first frequency band (eg, 13.56 MHz HF band) and a second frequency band (eg, 300 MHz band or 900 MHz UHF band). ) And an RFID tag function for transmitting and receiving RF signals.
The line electrode portion 22 functions as a loop (spiral) magnetic field radiation electrode in the portion from the outer peripheral end to the inner peripheral end of the spiral shape, and acts as an inductor, The other electrode 24 acts as a capacitor. The magnetic field radiation electrode portion 20 is configured by the line electrode portion 22, the electrodes 23 and 24 of the capacitive electrode portion, and the crossing line electrode 25. The inductor L and the capacitor C of the magnetic field radiation electrode unit 20 constitute an LC resonance circuit. The magnetic field radiation electrode section 20 functions as an antenna that receives (power receiving) an RF signal in the first frequency band.
The first wireless IC chip 61 rectifies the voltage generated between both ends of the electrode removal portion of the line electrode portion 22 and supplies the power to the RFID tag wireless IC 31 via the power supply lines 35 and 36. The first wireless IC chip 61 may be a simple rectifying element.
The RFID tag wireless IC 31 is a wireless IC for causing the wireless IC device 109 to function as an RFID. The RFID tag radio IC 31 operates using a voltage applied between the power supply lines 35 and 36 as a power source. In this way, by receiving power from the first wireless IC chip 61, the wireless IC device 109 can also function as an RFID using the first frequency band. Further, by receiving power from the first wireless IC chip 61 and further receiving power from the electromagnetic field by the second wireless IC chip 31 itself, both the first frequency band and the second frequency band are used. The wireless IC device 109 can also function as an RFID tag. The RFID tag radio IC 31 transmits and receives an RF signal having a second frequency by using the magnetic field radiation electrode unit 20 and the field radiation electrode unit 33 as a dipole antenna.
The principle that the magnetic field radiation electrode part 20 and the field radiation electrode part 33 act as a dipole antenna in the second frequency band is as already described in the first example .
In the above example, the first wireless IC chip 61 is directly connected to the line electrode unit 22, but an electromagnetic coupling module such as the electromagnetic coupling module 50 shown in FIG. 5 is configured and arranged. You may do it. Similarly, the second RF tag wireless IC 31 may be an electromagnetic coupling module. However, the supply of the power supply voltage is conducted in a DC manner.
Since a large amount of power can be received in the first frequency band having a low frequency in this way, the wireless IC device 109 can efficiently function as an RFID tag.
<< 10th example >>
FIG. 14 is a plan view of the wireless IC device 110 according to the tenth example . Unlike the wireless IC device 109 shown in FIG. 13A in the ninth example , the capacitor 71 is connected in parallel between the power supply paths 35 and 36. Therefore, the capacitor 71 smoothes and stores the power rectified by the first wireless IC chip 61. Even if the electric power excited by the magnetic field radiation electrode portion 20 is reduced and the electric power output from the first wireless IC chip 61 is reduced, the RFID tag wireless IC 31 has a stable power supply due to the storage function of the capacitor 71. Voltage is supplied. The capacitance of the capacitor 71 is determined according to the required operating time of the RFID tag wireless IC 31 in a state where the magnetic field radiation electrode unit 20 does not receive the RF signal in the first frequency band.
In place of the capacitor 71, a rechargeable battery may be provided.
According to the wireless IC device 110 according to the tenth example , since the power stored in the first frequency band can be transmitted and received in the second frequency band, reception of the RF signal in the first frequency band (HF band) is possible. And transmission and reception of RF signals in the second frequency band (UHF band) can be performed in the second frequency band even if they are not necessarily simultaneously performed. For this reason, the reader / writer using the first frequency band and the reader / writer using the second frequency band can be provided independently. Further, since the RF signal of the first frequency band and the RF signal of the second frequency band are transmitted at different timings, it is not necessary to match the transmission timings of the first frequency band and the second frequency band. , Control becomes easy.
<< Eleventh example >>
FIG. 15A is a plan view of the wireless IC device 111 according to the eleventh example . FIG. 15B is a plan view showing a state in which an electrode pattern is formed on the base material 21 which is one of the constituent elements 111 of the wireless IC device.
In the example shown in FIG. 13, the RFID tag wireless IC 31 and the first wireless IC chip 61 are individually mounted on the base material 21, but in the example shown in FIG. 15, a single wireless IC chip 62 is mounted. ing. The wireless IC chip 62 is a one-chip wireless IC chip having the function of the RFID tag wireless IC 31 and the function of the first wireless IC chip 61.

The wireless IC chip 62 includes a functional unit 31B equivalent to the RFID tag wireless IC 31 and a functional unit 61B equivalent to the first wireless IC chip 61. The ports P11 and P12 are connected so as to be inserted in the middle of the line electrode part 22. The port P <b> 21 is connected to a line connected to the front / back connection part 26, and the port P <b> 22 is connected to a line connected to the field emission electrode part 33.
The two functional units may be configured on a single semiconductor chip, or may be configured on separate chips and housed in a single package.
<< Twelfth example >>
FIG. 16A is a plan view of the wireless IC device 112 according to the twelfth example . The wireless IC device 112 includes a wireless IC chip 63 and a sensor chip 81. The sensor chip is a thermistor for detecting temperature, for example, and the wireless IC chip 63 measures the temperature using the sensor chip 81 and transmits the temperature information together with the unique information of the RFID tag.
FIG. 16B is a diagram showing an internal configuration of the wireless IC chip 63. The RFID tag wireless IC function unit 31B measures the temperature by directly or indirectly detecting the resistance value of the sensor chip 81 connected to the ports P31 and P32. Then, the RFID tag wireless IC function unit 31B transmits the RFID tag information and the measured temperature information by the RF signal in the second frequency band.
Note that the first wireless IC chip functional unit 61B may measure the temperature by directly or indirectly detecting the resistance value of the sensor chip 81. Further, the RFID tag information and the measured temperature information may be transmitted by the RF signal in the first frequency band.
<< 13th Example >>
FIG. 17 is a plan view of the wireless IC device 113 according to the thirteenth example . In the example shown in FIG. 13A, the magnetic field radiation electrode unit 20 is also used as one side of the dipole antenna in the second frequency band. However, in the wireless IC device 113 shown in FIG. Field emission electrode portions 33 and 37 that function as dipole antennas are provided.
In this manner, the field emission electrode portions 33 and 37 for transmitting and receiving the RF signal in the second frequency band are provided independently of the magnetic field radiation electrode portion 20 for receiving (power receiving) the RF signal in the first frequency band. Thus, the antenna of the first frequency band and the antenna of the second frequency band can be set independently.
<< 14th example >>
FIG. 18 is a plan view of the wireless IC device 114 according to the fourteenth example . In the example shown in FIG. 15A, the magnetic field radiation electrode unit 20 is also used as one side of the dipole antenna in the second frequency band. However, in the wireless IC device 114 shown in FIG. Field emission electrode portions 33 and 37 that function as dipole antennas are provided.

California Attorney General office did not file reply brief. Dragging it out for more time? Gary Michelson
David A Voet of the California Attorney General's office did not file his reply brief. I'm sure he will file his brief. I would bet he's just trying to get more time. Appellees did the same in my appeal. I then filed motion for sanctions as they filed two 60 day extensions then didn't file a brief. Within a day the Appellees in my case copied someone else's reply brief and filed that. I believe it was someone else's brief because it had the information of an Appellant other than me.
I just hope Neil and Richard win this thing soon. Their lives have already been destroyed. Gary took every penny they had and destroyed their reputations.

The state asked for their third extension. They first requested 60 days and got 30 days. Then at the end of 30 days they requested 30 more and received it. They just requested 30 more and got seven. I think the state is just extending things to drag things out as much as possible.

Mostafa Saber Mostafa Saber: On revolutions in Egypt, Tunisia, and Iran
1. The revolutions in Egypt, Tunisia, and of course Iran in 2009, despite their differences and distinctions, have common historical and universal characteristics. To categorize these revolutions (in the context of recent opposition and revolutionary movements in Yemen, Algeria and Jordan) as developments of the “Islamic world,” the “Arab world,” as “regional” (Middle East and North Africa), etc., explains some aspects of these developments, but ignores their essential characteristics and determinants. These popular revolutions and movements are the standard-bearers of a new revolutionary and radical era in the global arena. This is another page of the history of class struggle in the age of globalized capital, and if it does not have broader impacts than the “end of the Cold War” or “September 11” on the world’s appearance, it will not have less than them either. The difference is that if “the fall of the Soviet Union” and the “War on Terror” display the struggle between different bourgeois poles, and serve as launching boards for reaction and retrogression, the recent revolutions stand against those reactionary developments and mark the beginning of a period of direct and broad participation of the working class and revolutionary people in the shaping of global social changes.
The common denominator among all these changes is the ascent of radical popular movements that aim to change the status quo, which, at the end of the day, is a reflection of the contemporary proletarian class struggle against slavery and global capitalist reaction. In other words, after almost 4 decades, the offensive of the new right — empowered by the descent and defeat of bourgeois socialism and communism (both “Eastern” state capitalism of the Russian type and the “Western” state capitalism of the welfare state) — continued without pause and pushed the world to an unprecedented state of reaction and degradation. Now it has been more than a decade since radical left demands for justice and freedom, and workers’ demands for equality, step by step, have been emerging here and there, trying — by making mistakes and then learning from them, and even sometimes by acting as pressure groups for other movements instead of representing itself — to declare its own clear and undiscounted presence, a declaration that cannot be anything other than putting an end to wage slavery and abolishing the capitalist system and all of its symptoms.
The Middle East specifically, for historical reasons — including the issue of Palestine and the Arab-Israeli dispute, and the rise of political Islam (which was supported by the west in its empowerment of Khomeini to suppress the 1979 popular revolution in order to support the “Afghan Mujahedin” in drawing a “green belt” around the Soviet Union during the cold war era. In the aftermath of the crash of the Soviet Union, political Islam grew to fill the resultant vacuum, and a world with two fronts [‘the West’ and ‘political Islam’] eventually emerged; after September 11, a global reactionary pole prevailed) — has been the point of confluence of the world’s tensest crises, dead ends and military disputes for the past two decades.
6. In a more historical perspective, the objective meaning of the current changes and revolutions in the Middle East and North Africa is one of a revolutionary and popular initiative and attempt to completely transfer Arab-speaking and Islam-infested societies into the 21st century in all economic, social, cultural, and political dimensions. Based on these changes, the struggle between the two main social classes of the society — which is not only about how to integrate these societies into the 21st century, but is in its very essence about the definition of human societies in the 21st century — is going to intensify and take on new dimensions that expand beyond the region. The reality is that technological developments and unprecedented expansion of capitalism and global markets, which were explained above, not only resulted in an end to the main polarization of the Cold War era (i.e., the confrontation between the state capitalism of the East and free market capitalism of the west), but is going to end all hitherto bourgeois [divisions] or, redefine them according to the new balance of power and global capitalism’s needs. Thus, the division of the world between “industrial countries” and “the third world,” or other categories like “the Islamic world” or “the Arab world,” etc., will be put an end to. The world is moving inexorably towards a more homogenous culture and way of life. This historical inclination is primarily encouraged by capitalism in its own way, for more profitability, and therefore to equalize the status of the world’s proletariat. Capitalism naturally tends towards imposing ever-more arduous conditions on the entire world’s proletariat — in other words, the vast majority of contemporary human society. Politically speaking, this inevitably means pushing society towards retrogression and political reaction, towards police states, and towards attacking the rights and achievements that working and freedom-loving people have achieved thus far. This is a process the unfolding of which we have witnessed over the past 4 decades around the world. But history is not created by capitalism and bourgeoisie alone. To the contrary, and exactly against the political and economic tendencies of capitalism, the demands and tendencies of the proletariat — the vast human masses of our time who stand in defense of freedom and equality and prosperity and humanity — have found a global and common characteristic. Labor and social production have become global, as have peoples’ demands, from the level of wages and the degree of welfare, to political freedoms and individual and civil rights, to cultural preferences — all merge and unite and do so according to the highest global standards. This is a tendency that has, especially in the last decade, characterized various political movements, and we have witnessed their emergence throughout the world.

5.0 out of 5 starsGreat little regulator.
Holds a steady voltage when vehicle is stopped or running. Even during start I get a smooth 5 volt supply. This will supply my Arduino with a nice steady supply to run the boat sensors. Remains cool to the touch at this voltage and amperage. Will buy a second one for a 12 volt steady supply as well.
4.0 out of 5 starsIt's fun to play with
It's fun to play with. Very small unit, fits in my hand. I'm using a 19v laptop power supply to feed it. I then drop the voltage to whatever I need for a circuit. Basically using it as a mini variable voltage power supply.
I have 4 of these guys and they do exactly what they're supposed to do. I have them hooked up to some pretty high current draw motors, regularly pulling 3-8 amps with no problems. Easy to adjust the output voltage. Been using them to step down 24V to 12V. For the price they are excellent. Prime shipping too!
So far so good. I'm running about 60w through this guy and it gets pretty hot to the touch but no problems. It is advertised as being able to supply 100w without additional cooling.
3.0 out of 5 starsMine came broken
Mine came broken but I soldered it back together. Didn't have time to send it back and wait for another before I needed to use it.
quality seems good. I like that it has the option for adding a fan to keep it cool.
2.0 out of 5 starsNot recommended for loads over 5 amps
Works as advertised but the back requires a heat sink and heat transfer compound, and the mounting holes are to tight to the cooling fins. Not recommended for loads over 5 amps, or inputs over 24v.
5.0 out of 5 starsFor my bench.
I bought this so I could use it on my bench for those projects where I wanted a temporary supply for testing. Works great!!
5.0 out of 5 starsVoltage regulation was very good.
The regulator worked as advertised. Voltage regulation was very good.
Always gets the job done, nice high rated currents for robotics projects. Will continue to use these for my projects.
Works as advertised. Delivery was fast. Will buy more.
5.0 out of 5 starsWorks as per specs
Ran 24x7 for 1 month without problems.

DNCB Outing No. 2014-31 to Brunswick Point | Delta Nats Casual Birding / Delta Naturalists Society
← DNCB Outing No. 2014-30 to Iona Regional Park
Delta Nats Display at DCAS Animal Expo, Ladner →
DNCB at Brunswick Point (missing latecomers Al, Bryan & Janet) – click on photo to see large version
Photos by Jonathan, Terry, Glen, Liz, Marion & Ken on DNCB Picasa site
More than 20 “almost birders” enjoyed another gorgeous Delta morning wandering along the dike path at Brunswick Point. The Shorebirds are arriving here in big numbers for their “feeding pit-stop” on their way south and we had a few other hi-lites including Bullock’s Oriole and a sand-dusting Marsh Wren. Check out the photo evidence (photogs Jonathan, Liz, Terry, Marion, Glen, Ken) including the partial Group Photo on our DNCB Picasa site.
The ten “regulars” left Petra’s at 7:30 a.m. (4 vehicles – poor car-pooling) and our first stop was along the causeway to the Tsawwassen Ferry Port. The tide was very low so no birds were close. On the south side of the road we saw a pair of Black Oystercatchers with their son/daughter. A Cormorant swallowing a fish was neat. Near the ferry berths a small flock of Harlequin Ducks was loafing on the rocks just below us, but no Whimbrels seen. The rock island was surprisingly covered with more than 100 lazing Harbour Seals. We continued on through the TFN land and the Ladner fields to River Road and then to Brunswick Point where Ken (thankfully with his scope, but without Anne) and others were waiting or sporadically arrived soon thereafter.
Early birder Langley Tom spotted a Mink in the dyke rocks; coincidentally, Roger had stopped to photograph a roadkill Mink en route to Brunswick Point with his grandchildren.

Along the start of the trail several Cedar Waxwings were in the trees and House Finches and Savannah Sparrows in the bushes. Then we were surprised by a small bird sand-dusting itself in the middle of the path. This juvenile Marsh Wren was very accommodating, seemingly not bothered by us a mere 10 feet away. Mom made a fly-past and the youngster then took off after her. Further along we met Liz, then Aussie Nance, Langley Tom and Grandpa Roger with Jaeda and Ashley. American Goldfinches were everywhere. Also lots of Red-winged Blackbirds (and Brown-headed Cowbirds?) and European Starlings. Warblers were scarce, other than the occasional Common Yellowthroat. A few Northern Harriers glided by and a Bald Eagle with a huge rodent in its claws entertained the photogs. Various Wildflowers were in beautiful bloom and fortunately Jaeda & Ashley were able to identify several of them for us. It’s very refreshing, and helpful with their much keener eye sight, when young people like Julian and Roger’s grandkids join us on our outings.
On the path further along, closer to the shore, we finally saw some Shorebirds, Western Sandpipers and Killdeer. Terry got a photo of a Least Sandpiper too. In the bushes among the Goldfinches were a couple of young Bullock’s Orioles that the “good birders” saw and photographed. Others were watching a less-interesting White-crowned Sparrow. As we lounged in someone’s deck chairs on the shore, enjoying the ambiance, the cooing of Eurasian-collared Doves and time-challenged Bryan & Janet’s arrival, huge flocks of Swallows, mostly Barn with a few Tree Swallows, hawked insects around us and then landed in rows on lines and barn eaves. Although the tide was coming in, the large numbers of birds in the Strait on the horizon were too difficult to identify (mostly Gulls). White Rock Al (aka BOB Al, Birder on Bike) rode to the railway track end of the trail, but reported back saying he saw no new Shorebird species. As we walked back to our vehicles, more small swarms of Peeps were seen closer to shore, but it was approaching Noon so we couldn’t stay for the tide to bring them closer for better viewing. A Red-tailed Hawk circled above, not far from their nest near 28 Avenue, but we were blanked on the House Wren, apparently seen at Brunswick a few days earlier.
Some DNCBers continued on to Reifel and saw other Shorebirds including Dowitchers, Red-necked Phalarope, Yellowlegs, Semi-palmated Sandpipers and other Warblers (e.g. Wilson’s) and Waterfowl (e.g. Mergansers). Others went home to their spousal and grand-parenting duties, feeling exhilarated after another delightful morning outing.
Next Wednesday, August 13 we will have Roger’s Ferry outing to Galiano Island. We will meet at the Tsawwassen Ferry port around 9:30 a.m. and take the 10:20 a.m. ferry, returning on the 5:50 p.m. ferry, arriving at 6:45 p.m. Check out our DNCB Blog for more details about this outing, such as lunch plans, walking difficulty, etc. Each participant will be asked to donate 10 bucks so one or two DNCBers (Mike, WR Al?) can bring his vehicle for “island transport”. PLEASE EMAIL TOM or ROGER if you think you will be on the Galiano trip – pub needs to know approximate numbers for lunch.
Hope to see some of you this weekend at our Car Boot Sale on Saturday at Centennial Beach or the Animal Expo at Ladner Memorial Park on Sunday at our Nats Display booth. As always, your comments are encouraged, and please advise if you want off my List to receive this banter. Cheers: Tom
Next outing: Wednesday, August 13 to Galiano Island
– meet at Tsawwassen Ferry port around 9:30 am (suggest TFN parking with Shuttle bus)
– Ferry leaves 10:20, arrives 11:15 am
– returning from Galiano on 5:50 pm ferry, arr. Tsawwassen 6:45 pm

I respect others, and i have been respected by others.
I know that i were no good to be respected, i feel humble whenever people bid me. Cause i know that without you, there is no a word "respect" to me.
Remember dad; you said when i grown up, i going to be a great man.
Well daddy, here i am; neither a president nor a businessman. I'm just an Imam.
Now, in front of your pale and frozen body, my eyes was tearing, even my hand was shaking, yet my heart said something.
You are my love, my respect; a great man for myself.

8 Seconds–More than a Bull Riding Competition | TRI TO BE FUNNY: Carrie Barrett
January 30, 2009 by tritobefunny
8 Seconds–More than a Bull Riding Competition
Carrie Barrett’s 3M Half-Marathon Results
OK–not that it matters in the grand scheme of life, but it does matter to my pride and integrity.
When I finished Sunday’s 3M Half-Marathon, my Garmin read 1:32:54 when I stopped it.
However when official results were posted, I was credited for a 1:33:00-1:33:01 race (depending on which results you viewed). Thrilled with my PR and 8th place age group finish, I was still perplexed as to why my Garmin was so off from the official time. Did I stop it at some point on the run? Did I start it late? Am I that bad at timing? Am I imagining these PRs?
The same thing happened last Fall at the Marine Corps Marathon so I was beginning to think I’m crazy in the head…
Until the Official Photos were published this week:
That’s me stepping on the mat in what clearly reads on the Official Gun Time clock as 1:35:15. (FYI–I beat the Nike Shirt chick who is all in black just behind me) 🙂 See previous posts…
Now, if you scroll back up to my official results and look at my Gun Time, it reads, 1:35:23
The difference?! 8 FREAKIN SECONDS!!!
Or, a 1:32:53
Or a 6th place age group finish!
Again–not a big deal in life, but it solidifies in my mind that I am not a cheater or liar.
I did OFFICIALLY break my 1:33 goal mark (even though someone hasn’t changed the official results yet) 🙂
3M Half Marathon: Testament to Just Hangin’ On!!!
7 thoughts on “8 Seconds–More than a Bull Riding Competition”
Congrats! You are proving the inconsistency in technology! I think we should take this to the makers of all these products.
Don’t sweat the small stuff Carrie, you rocked!
Weird-o-rama. My chip time was 2 seconds faster than my Garmin time, which I figure is about right because I turn it on at the first of two chip mats at the start and off at the second of two at the finish. You got robbed!! But you still ran great.
Possibly the course was a little off in measurement so that everyone’s times were adjusted? Either way you ran a great race!
I think it was just Carrie – our times were spot on as well. Did you not remember to send an appropriate tribute to Raul before the race this time?
What a great race you had!!! Enjoy….
1) You are a rockstar and2) I’d be complaining to some race officials. Same thing happened to me a while back and it was the difference between breaking 2 hours and NOT breaking two hours.
