摘要

本文提出了一种新的双频选频器。该结构是由单波段选频谐振器扩展而来的。损耗层采用集总元件电容器和电感，无损层采用环槽双通带频率选择表面单元结构。仿真结果表明，该结构具有两个通带，谐振点分别为3.9 GHz和6.4 GHz，对应于−0.0383 dB和−0.4816 dB。通带两侧有三个吸收带。吸收频段分别为2.17 GHz ~ 2.6 GHz、4.89 GHz ~ 5.9 GHz和8.28 GHz ~ 9.1 GHz。带宽分别为0.43 GHz、1.02 GHz和0.82 GHz。40度以下吸收率70%，角度稳定性好。该结构对多波段扩展的研究具有重要意义。

A Dual-Band Frequency Selective Rasorber Design

A new dual-band frequency-selective rasorber is proposed in this paper. The structure is extended from single-band frequency-selective rasorber. The lossy layer uses lumped element capacitors and inductors, and the lossless layer uses ring slot dual-pass band frequency selective surface unit structure. The simulation results show that the structure has two passbands with resonance points of 3.9 GHz and 6.4 GHz, corresponding to − 0.0383 dB and −0.4816 dB. There are three absorption bands on both sides of the passband. The absorpted bands are 2.17 GHz∼2.6 GHz, 4.89 GHz∼5.9 GHz and 8.28 GHz∼9.1 GHz respectively. The bandwidth is 0.43 GHz, 1.02 GHz and 0.82 GHz, respectively. The absorption rate is 70% below 40 degrees, and the angle stability is good. The structure is of great significance to the study of multiband extension.
