Aims: In this paper, a comparison between three different human head models with three different types of antennas is presented to show the effect of shielding technique on the reduction of SAR. The three human head models presented are SAM phantom, six-layer, and two-tissue models. The three different types of antennas that are studied in this research are monopole, dipole, and helix antenna. Studying the parameters that affect the SAR value such as ferrite shield dimensions and position are also taken into consideration in this study to end up with a recommendation for the best model that achieves the optimum SAR reduction value. Place of Study: Department of Electronics and Communication Engineering, Faculty of Engineering, University of Zagazig. Results: The results have been obtained using CST Microwave Studio for the 3D EM simulation of high frequency components.
