Abstract :
The safety on human body against electromagnetic fields radiating from mobile devices has been investigated for a long time. The measurement method of RF power absorption to human body from wireless devices usually adopted robot scanning in the phantom in the past. But it takes a very long time to evaluate the SAR value of a mobile device. In this paper, a quick SAR measurement system using a 2D array of E-field probes having 3 axes isotropie characteristics is proposed. It is possible to fast estimate the volume SAR by a software with the 2D surface SAR data acquired by arrayed probes deleting robot moving time.
