1. An antenna array comprising:

  • a plurality of multi-layer substrates coupled to one another in a co-planar array, each including top and bottom ground planes and an inner conductive layer;

    a plurality of proximity coupled cavity backed patch antenna elements disposed on the plurality of multi-layer substates, each proximity coupled cavity back patch antenna element including plated through holes connecting the top and bottom ground planes of a multi-layer substrate around an element perimeter; and

    a plurality of distribution traces extending along the inner conductive layer of the substrates and coupling with the proximity coupled cavity backed patch antenna elements.
