摘要

频率选择面已成功应用于低雷达截面的雷达罩设计中。本文设计了Ku波段对大角度和极化不敏感的双层选频表面结构。根据FSS的物理结构,建立了等效电路模型,模型的上下两层可视为两个可碎的方环。利用电磁仿真软件HFSS对设计的模型进行了分析。最后,设计了一个波导缝隙天线来验证所设计的FSS。

High Angle Stability Frequency Selective Surface Design and Simulation
Frequency Selection Surface has been successfully used in radar radome design with low radar cross section. In this paper, a double-layer frequency selective surface structure with Ku band insensitive to large angle and polarization is designed. Based on the physical structure of FSS, the equivalent circuit model is established, and the upper and lower layers of the model can be regarded as two gristable square loops. The electromagnetic simulation software HFSS is used to analyze the designed model. Finally, a waveguide slot antenna is designed to verify the designed FSS.
