1. An antenna comprising:

  • an antenna feed to input a cylindrical feed wave that propagates outwardly and concentrically from the feed; and

    a radio-frequency (RF) tunable slotted array of a plurality of surface scattering antenna elements coupled to the antenna feed, wherein the cylindrical feed wave interacts with the RF array to generate a beam, wherein the RF array comprises a plurality of slots oriented at an angle relative to a propagation direction of cylindrical feed wave impinging at a central location of said each slot.
