摘要

本文基于天线滤波天线(AFA)的概念，采用亚波长单元设计了一种分形结构的多层频率选择表面(FSS)。上面的分形贴片是电感的，非谐振的，地面上的分形槽提供电容。薄衬底相当于变压器，形成谐振频率。细胞周期沿x和y方向相同，总高度为8mm (λ / 3.75，中心工作频率为10 GHz)。分数带宽达到30%。为了更好地分析和理解FSS的工作机理，提出了等效电路模型来分析FSS的传输和反射特性。仿真结果与综合结果吻合较好。

A novel subwavelength fractal frequency selective surface based on antenna-filter-antenna

In this paper, a novel multilayer frequency selective surface (FSS) with fractal structures is designed using subwavelength element based on the antenna-filter-antenna (AFA) concept. The upper fractal patches are inductive and non-resonant, and the fractal slots on the ground provide a capacitance. The thin substrate is equivalent to a transformer and a resonant frequency is formed. The cell periods along x and y directions are the same and the total height is the 8mm (λ / 3.75 at center operating frequency 10 GHz). Moreover, the fractional bandwidth reaches 30%. To well analyze and understand the operating mechanism of the FSS, the equivalent circuit model is proposed to analyze the transmission and reflection characteristics. The results of the simulation agree well with the results of the synthesis.
