SAR measurement for different antenna configurations

Abstract

Specific Absorption Rate (SAR) is a measure of radiation absorbed by the human body. SAR is expressed either as an average value of SAR in a cell of 1 gram or an average value in a cell of 10 grams. The aim of the paper is to study the average SAR value in human head due to the usage of mobile phones. The SAR values are measured and studied using a simulation software. In addition to calculating the SAR value, four different antenna configurations were designed with quarter-wave antennas to obtain the optimal design that has the least SAR value. The Specific Anthropomorphic Mannequin (SAM) phantom was used to simulate the human head and the simulation software was used to design the antennas and mobile phone.
