Design and implementation of implanted antenna inside a human body

The main objectives of this article is to design a microstrip antenna and discuss the effect of human tissues on its performance. This antenna will help in the future as a brainstorm to build a communication link with implanted devices to increase the capability of diagnosis and/or treatment and reduces the need for invasive surgical operations. It is pivotal to establish a low profile, small, safe and cost effective antenna in order to be utilized inside a realistic human body environment. The paper contains a cardioid patch antennas using microstrip feed. The antennas are simulated using CST microwave studio, fabricated and tested on the network analyzer. It operated from 3.5GHz to 10GHz. Based on simulation and measurement; it shows that the proposed antenna gives efficient agreement. For the investigation of the human tissues on some antenna parameters the rats are used to represent these issues.
