A numerical parametric study of SAR from a dual-band PIFA based antenna for mobile communication

Specific Absorption Rate (SAR) analysis is a vital part of compliance tests for commercial mobile phones performed in accordance with the set of comprehensive standardized practices provided by authoritative bodies. Dependence of SAR on a variety of parameters, with the structure of the handset pronounced the most, calls for bringing in the SAR analysis of various types of phones into the field of study for reference. This paper focuses on the SAR analysis of a PIFA based mobile phone antenna when operated next to standardized and anatomically correct head models. The effect of averaging method used, positioning of the phone, frequency of operation, and the presence of a homogeneous hand model on SAR is investigated along with the antenna performance in terms of terminal and radiational characteristics.
