Abstract

A pattern synthesis of an offset reflector antenna system using a five-bit phase-only controlled linear phased array feed is presented. Experimental results indicate this configuration can enhance the performance of an offset reflector antenna system in both polluted microwave and surface distortion environments. The implementation of a linear phased array feed in an offset reflector antenna system not only ameliorates reflector surface distortion, but also rejects jammers out of the antenna system by adjusting nulls to jammer directions. With this configuration, the reflector antenna system also has a larger scan angle than a traditional single feed reflector antenna system.<>
