In this paper we propose to attach radio frequency (RF) shields on mobile phone to reduce Specific Absorption Rate (SAR) in the spherical head model. Shields made of ferrimagnetic materials are used to suppress surface currents on the mobile phone. Many kinds of simulation are performed to investigate the effect of various parameters like location, size, shape and thickness of the shield on the SAR and also on the antenna performance using the field simulation software, CSTMicrowave studio (MWS).Paper includes numerical evaluation of the SAR reduction in the spherical head model and also analyzes the SAR data for shielding effectiveness.
