摘要
设计了一种X波段透射,Ku波段反射,具有大角度入射和较好极化稳定性的Y单元六边形紧凑排列的频率选择表面(FSS)。实测结果表明,当TE和TM波在±80°内入射时,该频率选择表面在中心频率9.41 GHz的5%带宽内透射损耗小于1 dB,同时在中心频率14. 5 GHz的5%带宽内反射率约大于90%。FSS在通带和反射都有着良好的角度稳定性和极化稳定性,对于分频复用的反射面天线和曲面流线型隐身雷达罩有很好的应用价值。
In this paper,a hexagonal frequency selective surface(FSS) with large incident angle and good polarization stability is designed. It realizes transmission at X band and reflection at Ku band. The measured results show that, when TE and TM waves arrive at ± 80 degrees, the transmission loss of this frequency selective surface in the 5% bandwidth of the center frequency 9. 41 GHz is less than 1 dB and the reflectivity in the 5%bandwidth of the center frequency 14. 5 GHz is greater than 90%. The FSS has good angle stability and polarization stability in pass band and reflection band. It has good application value for reflector antenna and streamlined stealth radome.
