Evaluation of Specific Absorption Rates with High Resolution Human Head Models at 890 MHz

We evaluated the spatially averaged 1- and 10-gram specific absorption rate (SAR)for PIFA (Planar Inverted- F Antenna)-type mobile phone antennas using three high-resolution surface-based human models. Use of these human models instead of the SAM (Specific Anthropomorphic Mannequin)phantom for SAR estimation significantly affected the SAR estimates. The obtained 1g and 10g peak SAR levels for the human models exceeded those for the SAM phantom by factors of three to four.
