Abstract
The base station has an antenna system comprising a housing for fixing it to a support and one or several radiating slots. It is designed for transmitting, in a first direction substantially perpendicular to the front surface of the housing, an electric field with polarization oriented along a second direction substantially parallel to the front surface, and for transmitting, in another direction closer to the second than to the first direction, an electric field with polarization substantially oriented along the first direction. The base station is well adapted to indoor environments in microcells or picocells. It can be fixed vertically on a wall or be horizontally suspended to a ceiling, without requiring separate antenna systems for these two installation modes.
