Abstract

We intend and design a new type of mobile handset antenna structure to reduce the specific absorption rate (SAR) in human head. The designed of low SAR handset antenna will be operating at 2.4 GHz frequency for wireless local area network (WLAN) by considering some parameters that determine the performance of the antenna. The authors carried out simulation by placing antenna at different position to determine position that are more suitable and effectively reduced the SAR level. The numerical results are compared and analyzed. The designed antenna operating at the range of frequency from 2373 to 2435 MHz with 2.6% bandwidth (BW) and the radiation pattern is omni-directional. The handset antenna design has achieved 1.483 W/kg for 1 gm SAR and 1.192 W/kg for 10 gm SAR which has been reduced for about 25.75% for 1 gm and 25.50% for 10 gm SAR value of the standard SAR level.
