| 摘 要： | 为了提高集总电容加载方形缝隙环频率选择表面(FSS)的设计效率,提出了FSS的等效电路模型,通过FSS单元的几何尺寸和加载电容参数直接计算出频响特性,简化了加载FSS的设计过程。根据等效电路模型设计了谐振频率为2.45 GHz的FSS,理论和实测参数曲线吻合很好。结果表明:该等效电路模型适合于微波低频段集总电容加载方形缝隙环FSS的快速设计与分析。

| Abstract: | In order to enhance the design efficiency of the square loop slot frequency selective surface(FSS)loading with lumped capacitance,an equivalent circuit model is proposed.The frequency response can be calculated directly based on the dimension of the FSS units and the parameters of the lumped elements,which greatly simplifies the process of the loaded FSS design.The FSS with resonant frequency 2.45 GHz is designed using the circuit model.Theoretical and experimental parameters of the FSS agree with each othe... |
