Size is important, but the correct size for the TV-frequency band is most important. The simplest antenna is a half-wave ...

A dipole antenna is easy, right? Two wires, each a quarter wavelength long, emanate from a coax or other feedline. Unless it is an off-center dipole. The length is still the same, but you move the ...

Every wireless device needs an antenna. This conductive mechanical device is the transducer that converts the radio frequency (RF) power to be transmitted into the electric and magnetic fields that ...
