Abstract
Despite numerous advantages, mobile phones cause serious health issues
to people due to electromagnetic radiation. Various head models already
exist to study the impact of radiation on a human head. The accuracy of
the measurement of power absorbed by different layers of a head should
be high. A new head model with six layers is proposed in this paper.
Parameters such as dielectric constant, conductivity and mass density of
different tissue layers skin, fat, bone, Dura, cerebrospinal fluid
(CSF), and brain are extracted from the Federal Communications
Commission (FCC) database. To study the impact of radiation in the
proposed model, standard planar inverted F-antennas (PIFA) capable to
radiate at 1.7 GHz and 2.4 GHz are used. Simulations are performed using
ANSYS Electromagnetics Suite. The analysis shows that the specific
absorption rate (SAR) in the brain layer decreased in the proposed model
when compared to the existing model.
