Abstract

An implantable CPW fed monopole antenna can be implemented in to human tissue is proposed for ISM band biomedical applications. The proposed antenna is made compatible for implantation by embedding it in an RT duroid substrate (Ωr=10.2 and thickness=0.65 mm) and also FR4 material (Ωr=4.6 and thickness=1.6 mm). The proposed antenna used for the ISM band of 2.45 GHz. The radiation parameters, such as return loss, E-Plane, H-Plane, are measured and analysed, using the CST software. The proposed antenna has advantages comparing other implanted antennas, like low profile, miniaturization, lower return loss, and better impedance matching.
