4G based SAR analysis for anatomically based human head model using mobile phone antenna

Abstract

Mobile phone handsets utilized by individuals of all ages been heavily grows popular as a wireless communication device. Every mobile phone produces electromagnetic radiation at radio frequencies (RF). The specific absorption rate is used to calculate how much of this energy is absorbed by the human skull. Standard guidelines state that sold phones must fall below a specified SAR. This paper aims to evaluate the Specific Absorption Rate (SAR) and E-field strength for mobile phone radiation exposure on a head model who is 40 years old and a 5-year-old child. The human skull is represented in this model as a six-layered sphere made up of the brain, CSF, dura, bone, fat, and skin. Various layers of the head's SAR distribution have been measured as an impact of radiation from mobile phones exposure using the 1800 MHz frequency. Earlier research were used to consider the dielectric properties of tissue layers. The human head and mobile phone antenna is modelled in this research using ANSYS HFSS. A hand-held mobile phone's dipole antenna type is considered for RF exposure. It is seen how EM absorption in various tissue layers for both adults as well as child head. SAR comparisons between the adult and child head reveal that the child head absorbs greater power due to the distinctive layerwise head shape, conductivity, permittivity, and permeability of the two head models. Excess EM absorption may have negative physiologic implications for human health specifically impact on child physical and mental health.
