A novel class of embroidered textile radio frequency (RF) circuit and antennas is presented. They are based on a new class of highly conductive metal-coated polymer fibers (e-fibers) and are used to realize a variety of wearable RF electronics woven into daily garments. The subject e-fibers are composed of high strength and flexible polymer core, typically 10um in thickness, and covered with a 2um thick metallic coating. Computerized embroidery machinery and high density stitching was employed to achieve high conductivity and precise fabrication of the e- fiber textiles woven into regular clothing. Using this process, prototype textile antennas and RF circuits were ''printed'' onto garments and evaluated. Their RF characteristics were measured in o -body (free-standing) and on-body con figurations. It is demonstrated that the textile antennas exhibit excellent RF performances, nearly as good as conventional copper antennas. This is in addition to their excellent mechanical strength and flexibility. Importantly, the textile antennas can be inconspicuously woven into clothing, without a ffecting comfort, fashionality, and washability. Consequently, various textile-based conformal and wearable antennas and sensors were designed and measured for communications, medical sensing, and RF energy harvesting applications. Overall, the proposed conductive textile-based antennas and RF circuitry provide solutions to future RF functionalized and fashionable garments for wearable wideband antennas with omni-directional coverage as well as frequency and beam recon figuration.
