The Embroidered Wearable Antenna for UWB Application

This paper discusses the design of a wearable textile antenna for Ultra Wide Band (UWB) application. This embroidered antenna addresses the issues of miniature size, wide bandwidth and low power consumption. A textile cotton has been chosen as a substrate and silver nylon plated yarn as a conductive element embroidered on cotton substrate. Simulated and measured results show that the proposed antenna design meets the requirements of wide working bandwidth with compact size and flexible material. The performances in terms of reflection coefficient, impedance bandwidth, current distribution as well as gain and antenna efficiency are compared between simulations and measurements and good agreement was observed.
