摘要

本文提出了一种超宽带双层吸收器，它由第一层电阻方形环和第二层电阻方形贴片组成。该设计在4.09-31.36 GHz范围内实现了27.27GHz的吸收带宽，吸收水平在90%以上，分数带宽FBW为153.85%，总厚度8.6mm，最低截止频率为0.117λ。本文还分析了所提工作的角稳定性，发现te模式的角稳定性可达80°。与以往的设计相比，所提出的设计在厚度带宽比上有了很大的提高

Double Layer-Resistive FSS Ultra Wideband Absorber with Improved Thickness to Bandwidth Ratio

This paper proposes ultra wideband double layer absorber, which consists of resistive square loop at the first layer and resistive square patch at the second layer. The design realizes an absorption bandwidth of 27.27GHz within 4.09-31.36 GHz for absorption level above 90% which has a fractional bandwidth FBW of 153.85% with an overall thickness 8.6mm, which is 0.117λ Lat the lowest cut-off frequency. The angular stability of the proposed work is also analysed and it is found stable up to 80° for TE-mode. The proposed design shows a great improvement in thickness to bandwidth ratio compared with previous work
