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