An active antenna array comprises: a digital signal processor connected to a plurality of digital-to-analogue conversion blocks; a plurality of antenna elements; a plurality of transmission paths, whereby an individual one of the plurality of transmission paths is connected between an individual one of the digital-to-analogue conversion blocks and an individual one of the plurality of antenna elements, whereby an individual one of the plurality of transmission paths comprises a correction signal combiner and a feedback coupler; a plurality of paths connected between individual ones of the feedback couplers and a single feedback combiner; a single feedback path connected between the single feedback combiner and a correction signal calculation unit; and a single correction signal path connected between the correction signal calculation unit and at least two of the correction signal combiners. A method for predistortion of radio signals in the active antenna array is also disclosed.
