为了实现双通带频率选择表面(FSS)在较厚介质基底、 较大频带间隔和入射角度下的工程应用, 设计制备了一种性能优良的Ku/Ka波段双频FSS结构. 利用FSS栅瓣图分析了FSS具有稳定滤波特性的条件. 应用矢量模式匹配法计算了基于分形技术和复合图形技术的FSS的传输特性. 根据单元谐振模式和FSS传输特性归纳了厚介质基底、较远双通带FSS的设计原则, 最终优化出一种由方环复合Y环单元组成的FSS结构. 结果表明: 该结构在6.7 mm厚介质基底上0-45扫描范围内, 在Ku/Ka波段具有稳定的双频传输特性, 透过率均优于75%. 这为设计基底厚度较大、频带间隔较远、入射角度要求较高的双带FSS结构提供了理论参考与实验依据.In order to make the dual-band frequency-selective surface (FSS) used in the engineering conditions of thick substrate, wide band spacing and large incident angle, an FSS structure with dual-band at Ku-band and Ka-band is presented. The stable filtering condition of the FSS is analyzed by using the grating lobe diagram, and the transmission of the FSS with combination or fractal elements is calculated using the vector modal matching method. The design method of the dual-band FSS with thick substrate is obtained by analyzing the resonance mode of the element and the transmission of the FSS. By using those methods, an FSS with combination elements of the square and Y loops is designed. The simulated and tested results show that the dual-bands of the structure at Ku-band and Ka-band are stable and the transmissions of the two pass-bands are larger than 75% when the incident angle is varied from normal to 45. This paper provides some theoretical and experimental references for the design of the dual-band FSS with thick substrate, wide band spacing and large incident angle.
