Abstract
In this work, we have presented a study of various antennas used in mobile phones in terms of their Specific Absorption Rates (SARs). Conventional antennas such as a half wavelength dipole antenna (0.835 GHz), rectangular patch antenna (0.8 GHz) and Planar Inverted F Antenna (PIFA) (0.8 GHz) are designed and simulated. In order to reduce their SAR values, Electromagnetic Band Gap (EBG) structure is placed near the dipole antenna. The various plots such as the S-parameter, radiation patterns and SAR values are generated to investigate results. The human head model with six layers having the appropriate material properties is designed to have a realistic approach in the detailed study on the SAR. All simulations are done in Ansys HFSS.
