Abstract

This letter presents a fully textile band-stop frequency selective surface (FSS) designed to wearable technologies applications. The proposed structure features a center frequency of 3.6 GHz and a bandwidth of 150 MHz. It consists of two semicircles connected by a central conductive line and was prototyped using a conductive thread on a cotton textile dielectric. The structure was experimentally validated in the laboratory, analyzing its performance for angles of incidence and polarization ranging from 0o to 45o. Additionally, the FSS was integrated into a data glove to investigate its capability for gesture recognition. Variations in the S21 magnitude and phase at the resonance frequency were successfully correlated with distinct hand gestures, showcasing its potential for applications in human motion monitoring. The results, obtained through both simulation and experimental measurements, demonstrate the versatility and feasibility of the proposed structure for flexible and wearable applications. All findings are presented and thoroughly discussed in this study.
