选频反射面隐身天线研究

FSS Reflector Antennas with Small RCS

利用频率选择表面(FSS)代替普通金属面构成选频反射面隐身天线。实验结果表明,该天线与原金属反射面相比,具有相同的辐射特性,但对带外威胁雷达波则可获得15dB左右的隐身效果。

By means of frequency selective surface (FSS) instead of metallic surface,a stealthy reflector antenna with small radar cross section (RCS) is constructed.The experimental results show this antenna can obtain about 15 dB of RCS reduction and similar radiation properties in comparison with ordinary metallic reflector antenna.
