| 摘 要： | 通过在矩形环为基本单元结构的基础之上设计了一种新型双频双极化低通高阻型频率选择表面（Frequency Selective Surface，FSS）。此结构将普通矩形环的每条边顺时针延长，再沿贴片的四周开槽矩形孔径后两边加载介质板的多层结构，实现了Ka波段带通、W波段带阻的空间滤波特性。经过电磁仿真软件HFSS的仿真与优化，所设计的新型扇形环状FSS结构在35GHz谐振频率处，插损为0.02dB，-0.5dB通带衰减带宽为5.85GHz;在94GHz谐振频率处，反射系数为-54.57dB，-20dB阻带带宽为4.29GHz，且在入射角0°~30°范围内具有良好的极化稳定性和角度不敏感性。

| Abstract: | A double-polarization, pass-band and stop-band frequency selective surface (FSS) based on the square ring element is presented for transmitting in Ka band and reflecting in W band. This structure is loaded on the middle of the two dielectric substrates, which is obtained by extending each edge of the ordinary rectangular ring, and then slotting rectangular aperture around the patch. Simulated results show that the insertion loss is about 0.02dB at 35GHz and the reflection coefficient is -54.57dB at 94 GHz. The -0.5dB pass-band bandwidth is about 5.85GHz in Ka band and the -20dB suppression bandwidth is about 4.29GHz in W band. In addition, the designed FSS structure has good characteristics in polarization-independent and angular-insensitive when the incident angles vary from 0° to 30°. |
