Abstract:
1. An active antenna array for a mobile communication network comprising: a plurality of first polarisation antenna elements being connected to a first protocol signal generator, the plurality of first polarisation antenna elements being adapted to radiate an individual first protocol transmit signal; a plurality of second polarisation antenna elements; an individual one of the plurality of second polarisation antenna elements being connected to an individual one of a plurality of second protocol signal generators, the plurality of second polarisation antenna elements being adapted to radiate, an individual second protocol transmit signal; at least one directional unit, wherein an individual one of the plurality of first polarisation antenna elements and the individual one of the plurality of second polarisation antenna elements are adapted to receive both an individual first protocol receive signal and an individual second protocol receive signal; and wherein the at least one directional unit is adapted to reduce a signal component of at least one of the individual first protocol receive signals being relayed along at least one of a first transmit path.
