Chip antenna layout suggests shorting feed line to ground?
Yes, that's correct. But keep in mind that at this frequency, any conductor of nonzero dimension is far from a &quot;direct short&quot;. In this case, it is partly the current flowing through the left-hand terminal that couples energy to the rest of the antenna chip. And because of the length and resulting impedance of that upper copper stub, there is also a voltage imposed along the length of the chip.
