SRR loaded CB-CPW fed hexagonal patch antenna for EEG monitoring applications

The new SRR loaded circular ring surrounded hexagonal patch shape conductor backed coplanar wave guide fed with configured wearable antenna is outstandingly necessary part for wearable device module for electroencephalogram (EEG) and healthcare monitoring. This antenna designed to fine-tune at resonating frequency 2.45GHz and 3.6GHz are one of the on-body narrow band communication and WLAN frequency band. This is SRR loaded antenna; hence it has high gain, bandwidth, flexible frequency tune, low-power consumption. The proposed model using a biocompatible material (Teflon) and SRR loaded structure, which is located in between radiation element and skin layer, therefore the designed antenna has enabled to have high gain and more isolation from skin layer. The simulated results for the magnitude of reflection coefficients are -16.5dB at 2.48GHz and -23.1dB at 3.6GHz for SRR loaded proposed antenna, -26.7dB at 2.47GHz and -13.39dB at 3.54GHz for non-SRR loaded proposed antenna respectively. These values are more suitable for standard ISM and WLAN communication.
