摘　　要：为降低频率选择反射面的设计维度和制造成本,研究了开口谐振环的结构尺寸对谐振点的影响,提出了一种双面印制型开口谐振环(Split-Ring Resonators,SRR)结构.利用负磁导率超材料,设计了一种双面印制型SRR结构,在平面内对SRR正交排列形成双面印制型频率选择反射面,对馈源频段的垂直极化波反射,而对其它频段来波透射.通过对新型频率选择反射面的测试,测试结果表明符合设计频率选择反射面(Frequency Selective Reflector,FSR)的反射性能.To reduce frequency selective reflector design dimension and manufacturing cost,the split-ring resonators is studied in the adjustment of the structure size effect on the resonance point,the double layers structure of split-ring resonators(SRR)is proposed.The double layers structure of split-ring resonators is designed,which is realized by utilizing the basic unit cells as negative magnetic conductivity of the metamaterials.The frequency selective reflector makes vertical polarized wave can be transmitted in source frequency band and other wave reflected.Based on the new frequency selective reflection test below,the test results show that the reflection performance meets the design requirements of frequency selective reflector(FSR).
