Design of SRR loaded CB-CPW fed diamond shaped patch on-body antenna for ECG monitoring applications

Abstract

The modern SRR loaded, circular ring encircled by a diamond shaped conductor backed coplanar wave guide fed with configured wearable antenna is exceptionally necessary part for wearable electronic tele-medical transceiver part of module, for electrocardiogram (ECG), electroencephalogram (EEG) and other healthcare monitoring. This antenna designed at resonating frequencies of 2.48GHz, 3.5GHz and 3.65GHz are one of the ISM on-body narrow band communication, Wi-Max, WLAN frequency bands. This is SRR and CSRR loaded antenna; hence it has high gain, bandwidth, flexible for frequency tune, low-power consumption, negative permittivity and permeability are obtained. The proposed model used as a biocompatible (Teflon) material as a substrate. The encircled loop structure and SRR and CSRR loaded arrangement, and which is located in between radiation element and skin layer, therefore the designed antenna has enabled to have more radiation, gain and more isolation from skin layer. The simulated results for the magnitude of reflection coefficients are −12.5dB at 2.49GHz and −31.1dB at 3.6GHz for SRR loaded proposed antenna, −25dB at 2.48GHz and −13.5dB at 3.54GHz for non-SRR loaded proposed antenna, −49.1dB at 3.57GHz, −42.3dB at 3.6GHz and −28.8dB at 3.66GHz for CSRR loaded antennas are used for interfacing between the WBAN to Wi-Max and WLAN networks, are respectively. These values are more suitable for the standard ISM, Wi-Max and WLAN communication.
