Abstract
An antenna system for a mobile communications base station and a method of operating a communications network including a base station is described. The antenna system includes an antenna array for beamforming and is configured either as a radar sensor, a communications antenna or a combined radar sensor. A radar image may be used to determine a map of objects in the vicinity of the antenna system and to adapt the beamsteering or beamforming of the antenna system.
Claims7
An antenna system for a mobile communications network base station, the antenna system comprising:
- an antenna array for beamforming, the antenna array comprising a plurality of patch antennas including two dual-polarized patch antennas including a first patch antenna and a second patch antenna;
- and
- a controller coupled to the antenna array for configuring each of the plurality of patch antennas to transmit or receive a Radio Frequency (RF) signal;
- wherein the controller is operable to:
- configure at least two antennas of the plurality of patch antennas to transmit and/or receive an RF communication signal in a first mode and to configure at least one antenna of the plurality of patch antennas to transmit a radar signal and at least one further antenna of the plurality of patch antennas to receive a reflection of the radar signal as a reflected radar signal in a second mode, wherein the controller is operable in the first mode to configure the first patch antenna in a first polarization and the second patch antenna in a second polarization and to either receive a communication signal detected via the first and second patch antennas or to transmit a communication signal via the first and second patch antennas.

An antenna system for a mobile communications network base station, the antenna system comprising:
- an antenna array for beamforming, the antenna array comprising a plurality of dual- polarized patch antennas arranged in an array having m rows and n columns, where m and n are non-zero positive integers;
- and
- a controller coupled to the antenna array for configuring each antenna of the plurality of dual-polarized patch antennas to transmit or receive a Radio Frequency (RF) signal;
- wherein the controller is operable to:
- (i) configure at least two antennas of the plurality of dual-polarized patch antennas to transmit and/or receive an RF communication signal and to configure at least one antenna of the plurality of dual-polarized patch antennas to transmit a radar signal and one antenna of the plurality of dual-polarized patch antennas to receive a reflection of the radar signal as a reflected radar signal;
- or
- (ii) configure at least two antennas of the plurality of dual-polarized patch antennas to transmit and/or receive an RF communication signal in a first mode and to configure at least one antenna of the plurality of dual-polarized patch antennas to transmit a radar signal and at least one further antenna of the plurality of dual-polarized patch antennas to receive a reflection of the radar signal as a reflected radar signal in a second mode;
- and
- wherein the controller is further operable to configure each patch antenna of the plurality of dual-polarized patch antennas in the same one of a first polarization and a second polarization.
