In this paper, Specific Absorption Rates (SAR) inside the human head and hand have been
analyzed for a handheld mobile phone with Planar Inverted-F Antenna (PIFA) is used to radiate
dual-band frequency of GSM 900/1800 MHz in the vicinity of the SAM head phantom.
Simulations are performedusing Three-dimensional Finite Integral technique (FIT) method via
CST-Microwave studio has been used to simulate SAR induced in the head and mobile.
Maximum peak 1-g and 10-g SARs of 0.5073 W/kg and 0.5479 W/kg are found at antenna
resonance frequency of 900 MHz for 0.125 W applied input power respectively, while maximum
peak 1-g and 10-g SARs of 0.762 W/kg and 0.9041W/kg at 1800 MHz for 0.250applied input
power respectively. All simulations are below the limits set by ANSI/IEEE and FCC.
