Abstract
This paper introduces the design, simulation and implementation of miniaturized printed monopole antenna for medical application. FR-4 substrate dielectric constant 4.3, and thickness 0.8 mm have been used. The proposed antenna operates in Medical Implant Communication System (MICS) band. It has a spiral shape with an overall dimension of (9x9x0.8) mm3. The proposed antenna was simulated and evaluated using the CST microwave studio package. The simulation results show that the designed antenna operates at a frequency of 401.3MHz with a return loss of (-10.904 dB) and bandwidth (3.9 MHz). The proposed antenna structure was fabricated and experimentally tested. Results of simulation and implementation show that the proposed antenna possesses a miniaturized dimensions and acceptable performances, enabling their use in medical applications
