A novel SRR loaded asymmetrical CPW fed ISM band wearable antenna for health monitoring applications

Abstract

A SRR loaded configured antenna is exceptionally essential part of transceiver module for wearable applications. The proposed coplanar waveguide (CPW) fed split ring resonator loaded wearable antenna will be used for short-distance ISM band biomedical communication for health care monitoring applications. This antenna is designed to fine-tune at resonating frequency 2.45GHz, one of industrial scientific-medical (ISM) band. This is meta-material based antenna; hence it has high gain, bandwidth, low-power consumption, less size and weight, low profile and conformal to on body-for high data rate wireless surface body communication. The main advantage of split ring resonator loaded antenna has enhanced the bandwidth and gain. The proposed model using a buffer layer, which is located in between radiation element and skin layer, therefore the designed antenna has enabled to high gain. The minimum return loss attains −41.2dB and −28.9dB at 2.45GHz respectively. The antenna required characteristic like such as far field configuration like, magnitude of reflection coefficient, VSWR and gain of the proposed antenna is presented.
