Implantable CPW fed dual folded dipole antenna for biomedical applications

Abstract

A implantable CPW fed dual folded dipole antenna operating in the ISM band (2.4-2.48 GHz) and WMTS (1.4-1.43 GHz) for biomedical applications. The proposed antenna is made compatible for implantation by embedding it in a biocompatible Poly Dimethyl Siloxane (PDMS). A study of sensitivity of the antenna performance as a function of the dielectric parameters of the environment in which it is immersed was performed. The proposed antenna is simulated using the method of moment's software IE3D by assuming the predetermined dielectric constant for the human muscle tissue, fat and skin and the parameters of the antenna such as return loss, radiation pattern, and VSWR are plotted.
