Summary:
Exposure evaluations of radio waves have been performed assuming the use of smartphones. A part of the frequency band used in fifth-generation mobile communication systems is allocated to mm-wave frequencies, and faster communication is expected to be realized. Therefore, it is necessary to evaluate human exposure to mm-wave band wireless communications using handsets. In this study, we evaluated the exposure to the human head using a mm-wave band handset by creating a model of a mm-wave antenna that can be embedded in a smartphone. We confirmed that electric fields are distributed over a wide area on the surface of the human head by placing mm-wave antennas at three locations in the smartphone model. For the next step, we plan to calculate the absorbed power density.
