Design of a Chip Printed Antenna at 4.8GHz for Wireless Implantable Body Area Network Applications

Abstract

The health monitoring system is improved by wireless implantable body area network technologies especially for medical diagnostic for instance blood pressure, breast cancer and heart attack. The objective of this paper is to design an implantable chip printed antenna at 4.8GHz for WiBAN applications. The antenna performances are evaluated in term of return loss, gain, efficiency, radiation pattern and operating bandwidth at different environments. In this experiment, the antenna is tested in three types of environments which are in homogeneous layer, non-homogeneous layer (skin, fat and muscle) and the real human hand voxel model from CST Microwave Studio Software. The simulations results of the antenna performances have been analyzed. Results proved that the resonant frequency and return loss are approximately similar for all environments. All the results will be guidelines in designing implantable antennas in futures.
