Design of UWB Antenna for Human Body Communication

Abstract

A diamond-shaped patch antenna with slots for desirable return loss, gain, and bandwidth was designed to achieve the intended goal. ROGERS 5880 was chosen as the substrate material and the antenna was simulated using CST (Computer simulation Technology) software. The designed microstrip patch antenna has a bandwidth from 2.12 to 9.24 GHz. The proposed antenna was put on the human body and had a SAR value of 1.44 W/kg, which was determined to be within the acceptable limit of 1.6 W/kg. Hence, the antenna can be used for on-body communication which is not detrimental to the human body.
