Ultra Wide Band Electromagnetic Shielding Through a Simple Single Layer Frequency Selective Surface

Published: 01 August 2017 Publication History

Abstract

Due to enormous increase of electromagnetic radiation emitted from proliferating radiating sources, precautionary approaches should be taken to minimize the resultant electromagnetic interference (EMI). Recognized as an effective countermeasure, electromagnetic shielding (EMS) structures are possible solutions for EMI cancellation. In this paper, a new filtering design is proposed with the aim of ultra-wide band EMS achievement and high signal attenuation. The proposed configuration, as a frequency selective surface, is composed of simple elements on both top and bottom layers of the substrate which exhibits 11.4 GHz ultra-wide stop band from 4.6 to 16 GHz. Moreover, in the aforementioned frequency bands, ultra-wide band shielding effectiveness with more than 20 dB attenuation is obtained as a more remarkable merit. The proposed design is a compact, simple, and suitable choice in shielding applications of ultra-wide frequency bands.
