Experimental Investigation into Frequency Characteristics of FSS Basic Aperture Cell

频率选择表面 (FSS )受到众多的设计参数的影响 ,十分复杂 ,通过实验手段研究FSS结构的基本振子的谐振特性是十分重要的。本文针对矩形缝隙这种基本FSS缝隙单元 ,在 8～ 1 7GHz频段上进行了扫频实验 ,由此分析和总结了几何参数和物理参数对其频率特性的影响 。

Because the design of FSS involves many parameters, it is necessaryto provide an insight into the harmonic characteristics of a certain class of FSS structure, especially, of dipole that is a basic aperture cell, by experimental investigations. Effects of geometrical and physical parameters on the frequency characteristics of the dipole are evaluated by the frequency sweep in a range of 8～17 Hz. Finally, the frequency characteristics as a function of geometrical and physical parameters are given.
