Analysis of a printed UWB micro strip antenna and the effects of human body in WBAN applications.

Abstract

This paper reports the SAR analysis performed to study the effects of the human body on the radiation parameters of a microstrip patch antenna designed on a Roger RT5880 substrate with a relative permittivity of 2.2. The CST Microwave Studio suite environment was used for design simulations, and the antenna was fabricated using MITS electronics’ Eleven Lab antenna printing machine. The printed antenna was placed near the human body to assess its performance in terms of return loss, bandwidth, realized gain, directivity, efficiency, and SAR. The SAR observed in the vicinity of the human body is within the IEEE standard. The designed antenna is hence proposed to be suitable for Wireless Body Area Networks (WBANs) applications.
