In this paper a new type of mobile handset antenna is designed to reduce the specific absorption rate (SAR) in human head using the slotting technique. In order to reduce SAR multiple slots have been etched on various places on the radiating patch. The new design for low SAR will be operating at multiband frequencies due to multiple slots. Apart from the SAR reduction various antenna parameters are also considered to be better in the proposed antenna. The proposed design obtained a return loss of -16db at 2.5 GHz, -12dB at 4GHz, -15dB at 5.4 GHz, -15dB at 7.4 GHZ and -14dB at 8GHz. In the proposed model the value of average SAR was reduced to 0.061732 W/kg over 10 g at the centre frequency 2.5 GHz. HFSS software is used to simulate the design.
