摘要:
基于工字型槽提出了两种三维频率选择表面(3-D FSS)结构. 通过在平行板路径金属壁上刻蚀工字型槽引入新的谐振模式,设计了一种具有椭圆滤波特性的单通带3-D FSS. 在此基础上,通过在平行板路径加载金属化过孔来构建双模谐振单元,平行板路径将原来单一的谐振模式分裂为奇偶模两种谐振模式,实现了一种高选择性、小通带比的双频3-D FSS. 通过对传输零点和极点处电场矢量分析,阐述了这两种FSS的工作原理. 同时,由HFSS软件仿真可知,所提出的两种FSS在TE和TM极化下不同角度入射时均具有较为稳定的频率响应.
Abstract:
Two three-dimensional frequency selective surface(3-D FSS)structures based on the I-shaped slots are proposed. A single-passband 3-D FSS with elliptical filtering characteristics is designed by introducing a new resonant mode by etching the I-shaped slots on the metal walls of the parallel plate path. On this basis,a dual-mode resonant unit is constructed by loading metallized vias in parallel plate paths. The parallel plate path splits the original single resonant mode into two modes of parity mode,achieving a dual-band 3-D FSS with high selectivity and small passband ratio. The E-field vector analysis of transmission poles and zeros is provided to understand the operating principle of the proposed two FSS. At the same time,it can be seen from the simulation of HFSS software that the proposed two FSS have a relatively stable frequency response under TE and TM polarization at different angles.
