摘要： 卡塞格伦天线和其它双反射面天线的雷达散射截面(RCS)是由天线本身的结构和增益决定的,它包括天线对来波直接散射构成的结构散射项σs和天线重新辐射来波而形成的模式散射项σe[1].入射到天线的电磁波先经主反射面聚焦到副反射面上,再由副反射面反射而进入馈源.

Abstract: A Cassegrain antenna with frequency selective subreflector is introduced, and the measured radiation Patterns and rsdar cross section (RCS) of the antenna are given. In comparison with ordinary metallic subreflector, this antenna can obtain similar radiation pattern and about 20dB of ROS redaction.This technique can be applied to ordinary dual reflector antonnas by simply changing the subreflector into FSS.

Key words: antenna, radar cross section, antenna scattering, frequency selective surface
