CIRCULAR SYMMETRIC DUAL REFLECTOR ANTENNA SYNTHESIS

摘要

This paper describes the synthesis of a symmetric dual reflector antenna for a deep space probe. The subreflector for the Cassegrain type high gain reflector antenna acts as a main reflector for a medium gain reflector antenna on the back surface. A comparison will be made between a ring focus type and a point focus type dual reflector antenna given the constraints of the medium gain antenna aperture.
