Performance Studies of UWB Microstrip Antenna for Multipurpose Biotelemetry Applications

Abstract

A unique small and flexible antenna operating in Ultra Wide Band (UWB) for Wireless Body Area Network (WBAN) applications is proposed in this article. The overall size of the antenna is 17.0 x 14.0 x 1.07 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> which is compatible to use with off-body, on-body as well as in-body wearable medical devices. The antenna, designed to use for biotelemetry application, has been experienced various performance studies like radiation pattern, bandwidth, directivity, gain, efficiency, Specific Absorption Rate(SAR). Simulation in a different medium which is needed for future implementation, is performed. Both planer and bending conditions are analyzed on and inside the human phantom model designed in CST MW Studio Suite. The designed antenna is aimed to use in the frequency range from 3.1 to 10.6 GHz with a remarkable return loss of -64.625dB for off-body and noteworthy results for on/inbody applications.
