Abstract

A novel, dual-band wearable textile antenna fabricated using conductive textiles for operation in both ISM and HiperLAN applications is presented. Its concept is based on the suspended-plate antenna. It features a 60 × 45 mm² rectangular radiating element suspended over a 80 × 60 mm² ground plane using a 5-mm foam substrate. The proposed rectangular radiator is modified using slots, slits, and shorting posts to enable dual-band resonance and broad bandwidths in both frequency bands: 277 MHz (2.22-2.48 GHz) in the ISM and 850 MHz (4.95-5.80 GHz) in the HiperLAN band. The antenna radiates unidirectionally, and the ground plane avoids coupling to the users´ body. The SP-WTA shows a total efficiency between 67% and 89% and a peak gain of 8.33 dB.
