Abstract

This research introduces an ultra-wideband frequency-selective surface (FSS) that offers a very good bandwidth for insulation and communication applications. It consists of two layers: a dielectric substrate layer and a metal layer. The basal layer, which is the substrate, is made of FR4; and the top patch, which is the metal, is made of copper. The FSS is constructed without using several layers or several resonators in a single unit cell. This single-sheet, planar-structure-based FSS has an ultra-level bandwidth of 20.3 GHz, ranging from 2.3 GHz to 22.6 GHz. It will be employed in microwave applications in the S, C, X, Ku, and K bands, with a centre frequency of 10.6 GHz. The polarisation and angle stability of the transverse electric (TE) and transverse magnetic (TM) modes are examined, and it was found that they are insensitive up to 90 degrees. Plots depicting the distribution of the magnetic field, surface current, and electric field are used to analyse the structure's physical mechanism. The performances from previous studies are compared and contrasted with that of the current work.

单层FSS，适用于s -， c -， x -， ku -和k -波段应用

本研究介绍了一种超宽带频率选择表面(FSS)，为绝缘和通信应用提供了非常好的带宽。它由两层组成:介电衬底层和金属层。所述基底层为基材，由FR4制成;最上面的那块是金属，是铜做的。FSS的构造不需要在单个单元电池中使用几层或几个谐振器。这种基于单片平面结构的FSS具有20.3 GHz的超高带宽，范围从2.3 GHz到22.6 GHz。它将用于S、C、X、Ku和K波段的微波应用，中心频率为10.6 GHz。研究了横向电(TE)和横向磁(TM)模式的极化稳定性和角度稳定性，发现它们在90度以内不敏感。用磁场、表面电流和电场的分布图来分析结构的物理机理。将前人的研究成果与当前的研究成果进行了比较和对比。
