NUMERICAL ANALYSIS OF LARGE REFLECTOR SYSTEM USED AS A GROUND STATION ANTENNA

摘要

In this paper we investigate a large dual-reflector (Cassegrain) antenna system, typically used as a ground station antenna in the space communication link. The study includes the blockage effects of the subreflector and the struts on the radiation performance of the antenna, as well as the estimation of the combination to the pattern degradation due to the panel gaps.
