Abstract :
A cavity surrounded stacked circular patch antenna is investigated as a feed for prime-focus reflectors in this paper. The radiation patterns of this feed are slightly asymmetric in the E-plane, which are improved by a differential feeding technique using two probes. This feed has a bandwidth of 20%, and wide beamwidths which improve the overall efficiency of symmetric parabolic reflector antennas.
