CPW fed monopole implantable antenna for 2.45 GHz ISM band applications

The present paper is a study on the design and characteristics of dual V shaped monopole antenna embedded in animal tissue and human body phantom liquid operating in the frequency of industrial, scientific and medical (ISM –915 MHz and 2.45 GHz) bands. This study proposes a prototype that is fabricated and tested in the parametric model of a coplanar waveguide-fed dual V shaped monopole antenna. To make the designed antenna suitable for implantation, it is embedded in an FR4 substrate (εr = 4.4 and thickness = 1.6 mm). The proposed antenna is simulated with help of IE3D simulator and measured by circumfusing in a human body phantom liquid. In this paper, the performance of implantable antenna in its dielectric parameter environment is studied. The experimental results show how the exhibited radiation performance strongly depends on design antenna parameters and resonant frequency. The simulated and experimental results demonstrate that the antenna covers the complete ISM band.
