ABSTRACT:
A plurality of antenna end-fire antenna feed elements at a corresponding plurality of locations and oriented in a corresponding plurality of directions on a third dielectric substrate cooperate with a discrete lens array comprising a plurality of electromagnetic lens elements, each of which comprises first and second broadside antenna elements adjacent to respective first and second dielectric substrates and a conductive layer therebetween, wherein the conductive layer is adapted with at least one coupling slot in cooperation with associated first and second broadside antenna elements so as to provide for a delay element operative between the first and second broadside antenna elements, wherein the coupling slots are adapted so that a delay period of at least one of the electromagnetic lens elements is different from a delay period of at least another of the electromagnetic lens elements so as to provide for a nominal focal surface of the dielectric lens.
