Shaping Design of Side-fed Offset Cassegrain Reflector Antennas

摘要：

The purpose of this paper is to improve the scanning performance of the Side-fed Offset Cassegrain (SFOC) reflector antenna by adjusting its reflectors shape. Firstly the ray-tracing technique is employed to obtain the path lengths and directions of the outgoing rays emanated from two specified feeds. Then the path length and direction errors of these rays are minimized by adjusting the antennas main-and sub-reflector surfaces. An optimization example of the SFOC antenna is provided for improving its wide-angle scanning performance, and the validity of the method presented is demonstrated.
