Abstract

This paper investigates the effect of radio frequency waves emitted by cellular phone antennas on the human head by using a 3D human head model to assess the specific absorption rate (SAR) in various human tissues. The simulation of SAR was performed using a PIFA (Planar Inverted-F Antenna) modelled in HFSS (High Frequency Structure Simulator) operating in the cellular frequency bands. To reduce the electromagnetic coupling between the mobile phone antenna and the human head, metamaterials were inserted at various locations in the vicinity of the antenna and study the effects of the metamaterial on the SAR level. The SAR in the human head was reduced by positioning the metamaterial between the PIFA antenna and the human head, with the metamaterial operating at a scale smaller than the wavelength of the antenna's operating frequency. The metamaterial structures exhibit resonance through internal capacitance and inductance, and a stop band was designed to align with the antenna's operating frequency band.
