  • 为了提高频率选择表面(FSS)设计优化速度, 利用等效电路方法对基于集总元件加载的微型化FSS结构进行了分析. 根据FSS物理结构建立了相应的等效电路模型, 通过ADS软件对全波分析曲线进行拟合提取了等效电路模型参数, 通过延长曲线范围增加极值点个数提高拟合参数精度. 利用所提取的等效电路参数计算了不同LC 参数下FSS的传输特性, 与全波分析精确结果相对比, 电路模型计算的透过率略高, 中心频点及-3 dB带宽与全波分析结果的相对误差均小于10%. 证明了利用等效电路模型分析复杂FSS结构的可行性, 为FSS设计和快速优化提供了参考.
    In order to quicken the pace of the frequency selective surface (FSS) design and optimization, an equivalent circuit method is used to analyze the miniaturized-element FSS structure loaded with lumped elements. According to the physical structure of the FSS, an equivalent circuit model is established. These parameters values of the equivalent circuit model are obtained by a curve-fitting process using ADS to obtain the best fitting between the circuit response and the full-wave analysis response. The fitting accuracy is improved by increasing the curve frequency and the extrema. By using the circuit model, the frequency responses of the FSS at different LC values of lumped components are obtained. The transmissions at center frequencies calculated by the circuit model are slight higher than the exact results from the full-wave analysis, and the relative errors between the center frequencies and the –3 dB bandwidths are smaller than 10%. This paper proves that it is feasible to analyze the complex FSS structure by the equivalent circuit model based on curve-fitting process. It will give some references to the quick design and optimization of the FSS.
