Abstract
A method and apparatus is disclosed herein for antenna element placement are disclosed. In one embodiment, an antenna comprises an antenna feed to input a cylindrical feed wave; a single physical antenna aperture having at least one antenna array of antenna elements, where the antenna elements are located on a plurality of concentric rings concentrically located relative to an antenna feed, wherein rings of the plurality of concentric rings are separated by a ring-to-ring distance, wherein a first distance between elements along rings of the plurality of concentric rings is a function of a second distance between rings of the plurality of concentric rings; and a controller to control each antenna element of the array separately using matrix drive circuitry, where each of the antenna elements is uniquely addressed by the matrix drive circuitry.
