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 to 2.48 GHz) in the ISM and 850 MHz (4.95 to 5.80 GHz) in the HiperLAN band. The antenna radiates uni-directionally 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.
