Wearable textile based MIMO antenna for 5G Application

A compact dual element MIMO antenna based on jeans material for wearable application is proposed in this communication. The proposed antenna is designed to cover upcoming 5G application band. A modified T-shaped open ended slot is implemented on the partial ground plane to optimize the isolation between the elements. The antenna exhibits an overall size of 0.537 λ0×0.326 λ0×0.016 λ0 covering the frequency range from 3.02 GHz to 4.5 GHz. The antenna maintains an isolation of −;21 dB over the desired frequency range. The antenna shows low envelope correlation co-efficient (ECC < 0.01) with high diversity gain (DG>>9.9) at the entire range. The antenna analysis is performing in human phantom for validating the wearable application scenario. Moreover, safety regulation is analyzed through the specific absorption rate.
