摘要

摘要:提出了一种偏振不敏感的三带通频率选择表面(FSS)。FSS在2.68 GHz、6.88 GHz和10.51 GHz频段的带宽分别为35.37%、11.86%和19.28%。该结构设计在单层FR4基板的一侧。在倾斜入射角为60°时,三个频段的插入损耗均优于-2 dB,证实了所提出的FSS的角稳定性。在27 × 27阵列的带通FSS样机上进行了测量,验证了仿真结果。

A Triple Band-Pass Polarization Insensitive and Angular Stable Frequency Selective Surface
Abstract-A polarization insensitive triple band-pass frequency selective surface (FSS) is proposed. The three passband of the FSS exhibits bandwidth of 35.37%, 11.86 %, 19.28 % centered at 2.68 GHz, 6.88 GHz and 10.51 GHz, respectively. The structure is designed on one side of a single-layer FR4 substrate. The insertion loss in the three bands is better than -2 dB up to an oblique incidence angle of 60 °, confirming the angular stability of the proposed FSS. The measurement carried out on the 27 x 27 array of fabricated prototype of the bandpass FSS validates the result obtained in simulation.
