Abstract
The effect of smart antennas on SAR at 1.9 GHz is investigated. We emulate the operation of the smart antennas by applying different signal weights (both phase and magnitude) to a mobile telephone prototype configured with two PIFA antennas. The SAR of this prototype is simulated using FDTD. It is found that the operation of smart antennas on SAR will have a significant impact, with SAR changing by ±3dB for varying signal or feed weights.
