Description
The investigations examined the impact of particular body parts (from both simplified and anatomically based models) on the parameters of radiation from the radiofrequency communication module (the parameters of performance of the modelled antenna operating at 2.45 GHz frequency) and the associated SAR. The preliminary results of these ongoing studies, obtained for an antenna-to-body distance of 2 mm, showed a reduction in a body-worn device’s antenna gain by (80-95)%, and an increase in the S11-linearly parameter by (20-35)% compared to the device operating in free space, while maintaining the same input power to antenna. They also revealed up to 30% variations of 10g-SAR in various adjacent body sections (head, arm, forearm).
