Analysis of reflector antenna system including frequency selective surfaces

Frequency selective surfaces (FSS) are often used in spaceborne applications of reflector antennas because of their ability to allow multiple feeds to utilize the same reflector dish. The problems inherent in evaluating the FSS separately from the reflector system are discussed. A method of integrating the FSS effects into the reflector system analysis is presented. An example is given for the proposed Advanced Tracking and Delay Relay Satellite System (ATDRSS) single-access triband reflector antenna.<
