Abstract
An apparatus is disclosed herein for a cylindrically fed antenna and method for using the same. In one embodiment, the antenna comprises: an antenna feed to input a cylindrical feed wave; a first layer coupled to the antenna feed and into which the feed wave propagates outwardly and concentrically from the feed; a second layer coupled to the first layer to cause the feed wave to be reflected at edges of the antenna and propagate inwardly through the second layer from the edges of the antenna; and a radio-frequency (RF) array coupled to the second layer, wherein the feed wave interacts with the RF array to generate a beam.
