Real tag antennas have some gain, but it is typically modest (around 2 dBi, since they are usually dipole-like), and since we don't always control the exact orientation of the tag antenna and may not ...

The dipole antenna is a half-wavelength structure made of wire, tubing, printed-circuit board (PCB) copper, or some other conductive material. It is divided into two equal quarter wavelengths and ...

Dipole antennas are easy, right? Just follow the formula, cut two pieces of wire, attach your feedline, and you’re on the air. But then again, maybe not. You’re always advised to cut t… ...

Circular polarization is less susceptible to signal fading since the polarization most easily propagated is achieved whatever the intervening propagation environment might happen to be. In ham radio, ...
