Implantable CPW fed circular slot antenna for ISM band

Abstract

In this paper, the CPW fed circular slot antennas are proposed for Industrial, Scientific, and Medical (ISM) band (2.4–2.48 GHz) applications. To make the designed antenna suitable for implantation, it is embedded in biocompatible Al 2 O 3 ceramic substrate. The antenna was simulated by immersing it in a phantom liquid, imitating the electrical properties of the human muscle tissue. A study of the sensitivity of the antenna performance as a function of its dielectric parameters of the environment in which it is immersed was performed. Simulations in various dimensions state demonstrate that the antenna covers the complete ISM band. The demonstration among the design EM characteristics of the antenna is presented by current distributions.
