The frequency response may also be controlled by a low voltage micro sized varicap, or a varactor diode, and instantiated as a tuned, resonant matching filter network residing with the antenna module.
The reflection characteristics of conical horn antenna are investigated by a new method which combines rigorous mode-matching approach with the multimode network theory.
