Abstract :
In this paper, accurate measurements for the SAR of modeled human heads using the brain equivalent phantom are presented. First, SARs of cubic and spherical phantoms in the vicinity of a dipole antenna are measured and compared with calculation. Secondly, a monopole antenna in a metal box, which simulates a mobile phone, is used. The operating frequency is considered only at 900 MHz. To enhance the accuracy of the experiments, the ingredients for the head model were carefully conditioned complying with COST 244 (1994)
