The purpose of this paper is to calculate the reduction of Specific absorption rate(SAR) using metamaterial attached to reactangular microstrip patch antenna operating at GSM 900 MHz. The FDTD method with lossy Drude model is adopted in this analysis by using CST Microwave studio. The SAR in the head can be reduced by placing metamaterial between human head and antenna used.Here we have used RMPA with m etamaterial substrate upon it.Using this, we have achieved a 97.99% reduction in case of 1g SAR and a 98.02% reduction for the case of 10g SAR.These results are useful in designing of safety communication equipments having low values of SAR .
