Analysis and design of CPW fed antenna at ISM band for biomedical applications

Abstract

In this paper, to design a patch antenna for implantable biomedical application in the frequency of ISM (industrial, scientific and medical) band (2450 MHz). The total size of the proposed antenna is 16 × 16 × 1 mm3 with the thickness of 1 mm, and this antenna is embedded in substrate (Teflon) with the dielectric constant value of 2.1 and loss tangent of 0.00028. The proposed antenna is simulated by using CST simulated and measured. The antenna parameters show good results such as lower return loss, perfect impedance matching, and better gain. The proposed antenna shows the better accuracy and performance compared to other conventional antennas. Keywords: Implantable antenna, Coplanar waveguide feed, ISM band biomedical applications
