1. A beam-forming network (BFN) for an emitting array antenna, having NB

  • 1 beam ports (BP), each corresponding to an antenna beam, and NE>

    1 antenna ports (AP), each corresponding to an antenna element, the network comprising;

    a multi-beam network (MBN) having at least NB input ports connected to respective beam ports of the beam-forming network and at least NOSA>

    1 output ports, for associating to each said output port a linear combination of input signals from respective input ports;

    a set of at least NOSA lossless single-mode networks (SMN), each having an input port (OSA-IP) connected to a respective output port of said multi-beam network OSA and at least NNOSAOSA>

    1 output ports, for associating to each said output port a signal obtained by weighting an input signal from said input port; and

    a set of at least NNOSA

    NNOSAOSA A lossless multi-mode networks (MMN), each having at least NNOSAOSA NOSANOSA input ports (NOSA-IP), each one connected to an output port of a respective single-mode network, and at least NENOSA>

    1 output ports connected to respective antenna ports of the beam-forming network, for associating to each said output port a linear combination of input signals from respective input ports.
