Computational Study of 5G Technology Dosimetry on SAM Human Head Model

Fifth generation (5G) technology is gradually introduced in the telecommunication infrastructure around the world. The current frequency range of such networks is 3.4-3.8 GHz (3.5GHz range), which is higher than prior networks to address the issue of increased capacity demands. However, such networks complicate the analysis of human exposure to electromagnetic field (i.e. it utilizes beamforming; requires denser network of access points to ensure adequate coverage). Additionally, since its initially introduction the public has been concerned with possible health influences and to date there is a lack of experimental validation of 5G network dosimetry in various scenarios. Hence, in the scope of this work, computation dosimetry study was performed by assessing the specific absorption rate (SAR) in a homogenous human head model induced by 3.5 GHz planar inverted F antenna fed by 0.2 W and placed at 10 and 15 mm from the head's surface. Such investigation serves as a foundation for modelling dose for epidemiological studies. The obtained results showed significant SAR values at the model's surface which drops to negligible levels in deeper sections of the model.
