A plurality of antenna end-fire antenna feed elements disposed along a contour on a dielectric substrate cooperate with a discrete lens array. An electromagnetic wave launched by an antenna feed element is received by a first set of patch antennas on a first side of the discrete lens array, and the associated received signals are propagated through associated delay elements to a corresponding second set of patch antennas on the opposite side of the discrete lens array from which the associated received signals are reradiated, wherein the corresponding delays of the associated delay elements are location dependent so as to emulate a dielectric electromagnetic lens and thereby provide for forming an associated beam of electromagnetic energy. A signal applied to a corporate feed port is switched to the antenna feed elements by a switching network, whereby different antenna feed elements generate different beams of electromagnetic energy in different directions.
