Hybrid system of electro-textile based wearable microstrip patch antenna with tuning holes

Abstract

In this paper the Utilization of textile materials for the development of flexible wearable systems has been rapid due to the recent miniaturization of wireless devices. As wearable computing is developing, there is an increasing need for a wireless wearable system with antennas playing a decisive role. There are much more applications involved if an antenna is made that are totally wearable The paper work here presents the design and fabricated output results of the textile antenna which is used for the 50 ohm system (as GPS or WLAN) at 2.4 GIIz As the textile material has higher resistivity the conductive textile has absolutely lower exterior resistivity than that of a untainted textile material the proposed antenna has an indirect hole for an improvement of the bandwidth and gain. The establishment side edges of the patch have been shortened to make available a further surface current path. The planned UWB wearable patch antenna purpose from 1 GIIz to 6 GIIz frequency range and it was successfully designed and the simulated result showed that the return loss was keep up less than -10 dB and VSWR kept less than 2 over the entire preferred frequency range (1 GIIz -6 GIIz). The performance of the antenna under bending condition is comparable with the normal condition's performance.
