A Multiband Textile-Based Metamaterial Absorber for WiMAX and WLAN Applications

Abstract

In this paper, a multi-band textile-based absorber design for WiMAX and WLAN bands is presented. The proposed absorber demonstrates an absorption spectrum of over 0.99 at 2.452 GHz, 3.504 GHz, and 5.264 GHz, as well as 0.80 absorption at 5.624 GHz. It also offers minimal cross-polarized impact on the frequencies of interest. All numerical analyses and designs were conducted using CST Studio Suite. This proposed structure is a good candidate for applications such as EMI/EMC, WiMAX/WLAN, and electromagnetic shielding.
