ABSTRACT:
A self-multiplexing antenna comprising an array of radiating elements for diating a plurality of orthogonal beams in response to wave energy excitations applied thereto. A plurality of first transmission lines are connected between respective radiating elements and respective resistive terminations. A plurality of second transmission lines are connected between respective input ports and respective resistive terminations. A plurality of directional couplers couple wave energy from each input port to each radiating element in the array via the first and second transmission lines whereby wave energy from each input port generates a separate orthogonal beam from the array of radiating elements.
