Embroidered wearable textile antenna on bending and wet performances for UWB reception

This research proposed an integration of the telecommu- nication system within garment and wearable product known as textile antenna. Such antenna performances on bending and wet conditions are discussed in the manuscript. This embroidered antenna provides a wide operating band satisfying an ultrawideband application of 3.1-10.6 GHz at 10 dB return loss. The proposed antenna is developed from a simple circular with T-slot structure and a partial ground plane. The fabricated textile antenna was made from both conductive and nonconductive wear- able materials. The simulated and measured bend angles of 20 � ,3 0 � , 40� ,5 0 � ,6 0 � ,7 0 � , and 80� is analyzed in terms of reflection coefficient via computer simulation technology software and programmable network analyzer, respectively. Moreover, the proposed embroidered antenna performance in wet conditions are investigated in four states of antenna inside water, antenna immediately wet, antenna approximately dry, and antenna completely dry. Simulated and measured results of reflection coefficient, surface current distribution, and gain are presented to vali- date the usefulness of the presented design. V C 2014 Wiley Periodicals, Inc.
