  A method to evaluate the statistical properties of the reception angle seen
at the input receiver that considers the receiving antenna pattern is
presented. In particular, the impact of the direction and beamwidth of the
antenna pattern on distribution of the reception angle is shown on the basis of
3D simulation studies. The obtained results show significant differences
between distributions of angle of arrival and angle of reception. This means
that the presented new method allows assessing the impact of the receiving
antenna pattern on the correlation and spectral characteristics at the receiver
input in simulation studies of wireless channel. The use of this method also
provides an opportunity for analysis of a co-existence between small cells and
wireless backhaul, what is currently a significant problem in designing 5G
networks.
