1. A digital beam-forming network (DBF) for an array antenna having N>

  • 1 antenna ports (EP), to be associated to respective antenna elements (RE), and M≧

    1 beam ports (BP), corresponding to respective antenna beams (AB), said digital beam-forming network comprising a plurality of complex weighting elements (CWE-SE, CWE-SB, CWE-SESB) interconnected through summing nodes (SN);

    wherein at least one of said complex weighting element is connected to either two antenna ports, to be associated to respective antenna elements which are arranged symmetrically with respect to a symmetry axis, or two beam ports corresponding to respective antenna beams pointing toward directions which are symmetrical with respect to a symmetry axis, or both.
