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
