摘要
提出一种宽频带、低插损的单元小型化频率选择表面(FSS)新型设计。在经典方环型频率选择表面单元基础上进行设计,通过增加方环曲折缝隙的方法,在不增大单元面积的同时降低单元的谐振频率,同时采用中心对称结构降低频率随入射角度的改变增加角度稳定性以及极化稳定性。将这种新型频率选择表面单元与方环贴片型频率选择表面单元级联,通过介质层的合理加载,设计出一个三层的频率选择表面,所实现的低频段带通特性带内差损小、带宽宽以及角度稳定性好。
This paper presents a new miniaturized Frequency Selective Surface （FSS） element with wide bandwidth and stable polarization and angular responses.By maneuvering the slot of a classic square ring type FSS, the resonant frequency of the element was greatly decreased.At the same time,the element exhibits excellent angular stability and polarization stability due to its center symmetric structure.Cascading the new element with square ring patch FSS elements loaded with dielectric layers, a three-layer-FSS was designed.which has an insertion loss less than 2dB in a bandwidth of 80%.
