摘要
利用具有带阻选频特性的周期结构表面替代普通金属反射面构成的滤波反射面天线是一项克服天线散射的有效技术途径.本文给出了滤波反射面天线辐射特性和RCS的实测结果;分析讨论了此种天线的性能和可行性.
A Cassegrain antenna with frequency seletctive reflector is introduced, and the measured radiation properties and radar cross-section (RCS) of the antenna are give and discussed. In comparison with ordinary metailic reflector, this antenna can obtain similar radiation pattern and about t5dB of RCS red■ion.
