Performance Analysis of a Microstrip Patch Antenna for Biomedical Applications

Abstract

A microstrip patch antenna’s design and performance analysis for biomedical applications which operating at 2.45 GHz frequency range in ISM Band (2.4 GHz to 2.5 GHz) is represented in this paper. The antenna’s goodlooking feature is the proper thickness and suitable dimension. The special feature of this antenna is to make it perfect for Onbody matched biomedical applications. FR4 material is used as the substrate to design the antenna. Individual properties of the Phantom model are perfectly maintained to get proper software simulated result. All the simulations, calculations and parameter results are fit for on-body matched conditions. To design the antenna CST Microwave Studio is used. Impressive S11 of more than ˗50 dB for off-body and on-body as well as Specific absorption rate (SAR) of 0.0005 W/kg in on-body make the antenna compatible for biomedical application.
