Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.
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.
