摘要
研究了由方型缝隙单元和十字贴片组成的互补结构有源频率选择表面(Frequency-selective surface,FSS)的传输特性。通过HFSS仿真和实物测试,给出了PIN管不同工作状态下的插入损耗和插入相移,研究了该结构的角度稳定性。数据结果表明,通过改变PIN管的工作状态,在谐振点处插损有17dB的动态变化范围,从而为有源FSS天线罩的设计提供参考和借鉴。
Transmission characteristic of complementary active frequency-selective surface （FSS） consisting of square aperture unit and cross patch unit is investigated. Simulated and measured insertion loss, insertion phase delay and angle stability are presented under different PIN states. The results show that there changing the PIN status. The results will is a 17 dB dynamic change of transmission loss by benefit to the design of active FSS radome.
