Abstract
In this paper, the human shadowing effect is
studied at the millimeter-wave band centered at 28 GHz.
The analysis takes a holistic view of the opportunities and
challenges that are brought by the presence of a human in
the millimeter-wave channel. The impact of human body
shadowing on the antenna array performance is investigated,
where the impairments due to the non-stationarity
over the antenna array caused by human-induced shadowing
are presented. The spatial-delay information is obtained
using a frequency-invariant beamforming algorithm. The
measured channel in a free space scenario is compared with
the channel when a human subject and a metallic cylinder
of similar size to the human subject are present in the
channel. The results show that despite a high shadowing
attenuation when the human blocks the propagation paths,
there are opportunities presented by the presence of the
human which can enhance the spatial diversity of the
channel at some spatial locations.
