Impact of the International Standardization of SAR Compliance Testing

Worldwide harmonization of SAR compliance testing methodologies have led to changes from previously used procedure and equipment. This study focuses on the impact of the introduction of the Specific Anthropomorphic Mannequin (SAM) phantom, different dielectric properties of the tissue simulating liquid, and the 15 degree tilt device position on SAR measurement. The assessment was performed using 4 actual phones and two generic phone models with monopole antennas powered by an external RF source. The results of this study show that the new requirements impact SAR and generate even more conservative results than previous tests.
