摘要: In this paper, a novel textile antenna with semi elliptical ground plane is designed for ultra-wideband applications. Conductive woven fabric made of stainless steel/polyester (80/20%) spun yarn 158 Ω/m linear resistance used to design the and patch antenna. Moreover, warp density weft are selected in way that it gets high value surface conductivity. The conductivity was 0.088 Ω/sq. proposed triangle within transmission line its dimensions optimized using genetic algorithm. Results show achieves multi impedance bandwidth ranging from 1.4 1.6 GHz, 1.8 2.4 GHz, 3.4 11.6 GHz (reflection coefficient <−10 dB). both bands 1.6 GHz 2.4 GHz circularly polarized. This makes appropriate many wireless communication systems such as GPS, Wifi, PCS-1900, IMT-2000/UMTS, a...
