Abstract :
In this paper, the CPW fed Z monopole antennas has proposed for Industrial, Scientific, and Medical (ISM) band (2.4-2.48 GHz) applications. To make the designed antenna suitable for implantation, it is printed on biocompatible Al2O3 ceramic substrate. The proposed antenna was simulated by a phantom liquid and imitating the electrical properties of the human muscle tissue. A study of the understanding of the antenna performance as a function of its dielectric parameters of the environment in which it is immersed was performed. Simulations in various slot widths state demonstrate that the antenna covers the complete ISM band. The proposed antenna shows the lower return loss, good impedance matching and high gain compared to other implantable antennas.
