Fully Textile Inked FSS for Wearable Applications

Abstract This paper presents a fully textile band-stop frequency selective surface (FSS) designed with a central frequency of 3.6 GHz and a bandwidth of 190 MHz. The structure, composed of two semicircles connected by a central line, was designed, fabricated, and experimentally validated. The prototype was created using copper ink on a pure cotton fabric substrate and tested in the laboratory for incident angles and polarizations ranging from 0° to 45°. Additionally, the structure’s performance was examined under two different curvatures. All simulated and experimental results are provided and analyzed.
