摘　　要：提出了一种具有双频特性的小型化带阻频率选择表面(Bandstop Frequency Selective Surface,BS-FSS)结构,通过调节所提出单元的结构参数可以实现对BS-FSS谐振频率的独立控制,在此基础上,设计了一款工作在3.84GHZ和6.67GHz的BS-FSS。仿真结果表明:所设计的BS-FSS的相对带宽分别为57.8%和12.9%,并且在工作频段内,对TE波和TM波均具有较好的极化、角度稳定度。此外,在相同介质条件下,设计的BS-FSS单元物理尺寸为7 mm×7mm,相比于传统的FSS单元,整体尺寸减小了56.9%,小型化优势显著。A miniaturized dual-band band-stop frequency selective surface （BS-FSS）is proposed and ana-lyzed.The resonance frequencies of the proposed BS-FSS can be adj usted by changing the structure param-eters,and a miniaturized BS-FSS centered at 3.84 GHz and 6.67 GHz is designed and simulated.The simu-lated results indicate that the designed BS-FSS obtains bandwidths of 57.8% at 3.84 GHz and 12.9% at 6.67% GHz,and performs very well in the angle stability and the polarization stability within the operat-ing bands.Besides,a whole size of the proposed BS-FSS unit cell is only 7＆#215;7 mm2,compared with the conventional FSS unit,the integral size is reduced by 5 6 .9% at least,and the advantages of miniaturization are obvious.
