Verification and validation in computational simulations of Specific Absorption Rate for a multi- band handheld device

This paper provides a comparative analysis of specific absorption rate (SAR) simulations and measurements for a handheld device. The numerical structure of the device under test (DUT) was modeled according to real passive devices. After making sure of the Total Radiated Power (TRP), SAR Comparison of Measurement and analysis were performed by using the standard phantoms. DUT is the most commonly used design in display only phones, and supports E-GSM900, GSM1800, WCDMA B1 and B8 bands. The radiated structure was designed with antenna and feedings equal to a real model including all other components. The radiated power, SAR and E-field distribution were compared simulations and measurements with the phantoms of the head, body and limb in accordance with international standards.
