1. A modular beamformer for providing millimeter-wave signals to a plurality of radiating elements of a phased array antenna, the beamformer comprising:

  • a plurality of substantially identical beamformer modules arranged in a stacked configuration, each beamformer module being in a primary plane; and

    a plurality of feeder lines extending through each beamformer module of the plurality, each feeder line coupled to one of the radiating elements,wherein each beamformer module comprises;

    a plurality of Gallium Arsenide (GaAs) Monolithic Microwave Integrated Circuit (MMIC) phase shifter elements for providing phase-shifted signals to more than one of the feeder lines; and

    an input signal path interconnecting each one of the plurality of phase shifter elements,wherein each feeder line is arranged in a secondary plane substantially perpendicular the primary plane, each one of the feeder lines comprising a dielectrically loaded wave guide.
