摘　　要：频率选择表面(frequency selective surface,FSS)的研究中,小型化设计一直是研究的热点内容之一,小型化单元结构可以很好地增加FSS的稳定性.文章利用液晶材料给出一种基于三层互耦结构的可调谐FSS单元的设计,为了将每个单元的金属结构连接起来,添加了集总元件来馈电.结果表明,该结构单元尺寸相当于工作波长的1/16,连续可调谐范围可达11.3%.本文所设计结构具有小型化和可调谐的特性,为FSS的设计提供了新的设计思路,具有一定的理论指导意义和实用价值.In the research of frequency selective surface(FSS),miniaturization design has always been one of the hot topics of research,and the miniaturized unit structure can greatly improve the stability of FSS.In this paper,a liquid crystal material is used to design a tunable FSS unit based on a three-layer mutual coupling structure.In order to connect the metal structures of each unit,a lumped element is added to feed.The results show that the size of the structural unit is equivalent to 1/16 of the operating wavelength,and the continuous tunable range is up to 11.3%.The structure designed in this paper has the characteristics of miniaturization and tunability,which provides a new design idea for the design of FSS,and has certain theoretical guiding significance and practical value.
