A Coplanar Wave Guide Fed Triangular Shaped Implantable Antenna for Industrial Scientific Medical Radio Applications

This paper presents a conductor-backed coplanar waveguide (CB-CPW) fed triple circular and triangular-shaped antenna for industrial medical service (ISM) band applications. The designed antenna consists of three circular and triangle-shaped patches with muscle layers. The designed patch has a micro-size of dimension 0.02λo×0.02λo×0.003λo. The return losses are 19dB for with tissue and 18dB for without tissue obtained at an ISM-based resonance frequency of 5.8GHz. The foremost advantages of this model are micro size, high gain, and bandwidth. The designed antenna is constructed by an FR-4 substrate. The standard parametric result of this designed prototype model indicated that this is the best device for ISM band (5.7-5.8GHz) based healthcare monitoring applications.
