Performance analysis of novel coplanar waveguide fed slot antenna for ECG monitoring

In this study, a unique ECG slotted patch antenna loaded with split ring resonator is designed and analyzed for ECG monitoring. The antenna is fed with conductor backed coplanar feed to obtain low dispersion and attenuation characteristics. The operating frequency of the designed antenna is in the Industrial Scientific medical band (2.4 to 2.5) GHz. Performance analysis is made for both FR4 and PDMS substrate. The results of the proposed antenna’s specific absorption ratio and return loss are 0.487 W/kg and21. S7dB for FR4 and 0.2604 W/kg and -31.4S dB for PDMS. A comparison on gain, directivity, return loss and SAR is presented.
