Abstract: An antenna system is provided for producing a plurality of differently directed beams of electromagnetic energy, each one of such beams being associated with a corresponding one of a plurality of beam ports, each one of such beams being produced from a common array of antenna elements. The antenna system includes a radar frequency energy lens assembly having a plurality of array ports coupled to the plurality of antenna elements. The lens assembly includes a radio frequency lens having a plurality of lens ports disposed about peripheral portions thereof. Each one of a first portion of such plurality of lens ports is coupled to a corresponding one of the antenna elements through a corresponding one of the array ports and each one of a second, opposing portion of the plurality of lens ports being coupled to a corresponding one of the beam ports. Each one of the lens ports in one of the portions thereof includes a pair of tapered feeds.
