Exposure Assessment of a 5G indoor planar array antenna using Computational Dosimetry

The following work is focused on the assessment of exposure levels in indoor environment, taking account the innovations of the upcoming 5G network technology. More in details, it was analyzed the exposure caused by a 5G access point in a room, modelled with an indoor 8x8 planar array antenna. The working frequency of the planar array antenna was selected according to the frequency range that will be used firstly in Italian 5G networks and will be 3.7 GHz. The exposure levels were assessed using the Ella model from the Virtual family. The quantity analyzed will be the specific absorption rate in the head tissues.
