Abstract: A multiple-input multiple-output (MIMO) antenna system for a mobile cellular network and method is described. The MIMO antenna system includes an array of dual-polarization patch antennas each having first and second polarization feed-points. A signal is transmitted via the first polarization feed-point of a dual-polarisation patch antennas and a replica of the transmitted signal is sensed (detected) using the second polarization feed-point of the same patch antenna. This replica signal is used by a digital predistortion module to apply predistortion to a subsequently transmitted signal.
