  With the proliferation of 5G wireless networks, the population is
increasingly exposed to frequencies approaching the millimeter-wave (mmW)
range. Human ears are among the most exposed body parts. This paper proposes an
analysis of the ear exposure in the near field using an anatomical model in
presence of different electromagnetic (EM) sources (vertical dipole, horizontal
dipole, 4X4 array of vertical dipoles, and 4X4 array of horizontal dipoles).
This study demonstrates that, for a given input power and antenna-ear distance,
the absorbed power density (Sab) induced by a dipole antenna array is up to 3.9
times higher than the one produced by a single dipole. Sab is only slightly
sensitive to the dipole orientation (vertical or horizontal) resulting in
relatively weak variations (up to 7%).
