An important class of radio antenna is the thin element antenna in which the radiating elements are conductive wires or rods. These include monopole antennas and dipole antennas, as well as antennas based on them such as the whip antenna, T antenna, mast radiator, Yagi, log periodic, and turnstile antennas. These are resonant antennas, in which the radio frequency electric currents travel back and forth in the antenna conductors, reflecting from the ends.
