Abstract

Cellular phone protection and the enforcement of pertinent exposure standards are issues in the current media, and regulatory agencies are motivated to ensure that compliance testing is acceptable. This is important because the electromagnetic radiation towards human being will heat the human tissue especially our brain as it is the most sensitive organ. In this project, the main objective is to design an antenna which has low SAR value than mentioned above. Besides that, the designed 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 were carried out simulation by placing antenna at different position to determine which position are more suitable and effectively reduced the SAR level. The simulation results are compared and analyzed. The designed antenna operating at the range of frequency from 2373 MHz to 2435 MHz with 2.6% bandwidth 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 reduction about 25.75% for 1 gm and 25.50% for 10 gm SAR value of the standard SAR level. It is demonstrated that the novel design of the low SAR antenna doesn't degrade its RF performance though has a great advantage of reducing the SAR value inside the user's head.
