摘要

本信提出了一种具有宽高传输通带的双偏振 C-X-Ku 波段选频干扰器（FSR）。所提出的 FSR 由带内栅交叉框架的有损耗层和非谐振无损耗层级联而成。这种结构可同时实现极化不敏感性、角度稳定性和宽带性能。仿真结果表明，-1 dB 的透射率范围为 10.10 至 13.01 GHz，分数带宽为 25.2%。低于 -10 dB 的反射率范围为 4.19 至 17.81 GHz，分数带宽为 123.8%。双极化模式下的稳定吸收和传输特性可维持到 30$^\circ$。我们制作了拟议 FSR 的原型，测量结果与仿真结果吻合。所提出的设计可以成为隐形天线罩封闭宽带天线的理想方案。

A Dual-Polarized C-X-Ku-Band Frequency-Selective Rasorber With Wide High-Transmission Passband

A dual-polarized C-X-Ku-band frequency-selective rasorber (FSR) with a wide high-transmission passband is proposed in this letter. The proposed FSR is formed by cascading an lossy layer with inner-gate cross frame and a nonresonant lossless layer. This structure can simultaneously achieve polarization insensitivity, angular stability and wideband performance. The simulation results show that the transmissivity of −1 dB ranges from 10.10 to 13.01 GHz, with a fractional bandwidth of 25.2%. The reflectivity below −10 dB ranges from 4.19 to 17.81 GHz, with a fractional bandwidth of 123.8%. The stable absorption and transmission characteristics in dual-polarization mode are maintained up to 30

$^\circ$

. A prototype of the proposed FSR is fabricated and the measurement agrees well with the simulation. The proposed design can be a desirable scheme for broadband antennas enclosed by stealth radomes.
