Abstract
In order to receive simultaneously signals with different polarizations, the antenna feeding system is adapted to comprise diplexers and a hybrid circuit for synthesizing signals, which are transmitted through signal paths allocated to the frequency of a circularly polarized wave from the diplexers, upon giving 90° phase difference therebetween and for selectively outputting the synthesized signal to either one of signal terminal for right handed circularly polarized wave or for left handed circularly polarized wave.
