Abstract
A method and apparatus for aperture segmentation are disclosed. In one embodiment, the antenna comprises an antenna feed to input a cylindrical feed wave and a physical antenna aperture coupled to the antenna feed and comprising a plurality of segments having antenna elements that form a plurality of closed concentric rings of antenna elements when combined, where the plurality of concentric rings are concentric with respect to the antenna feed.

A flat panel antenna comprising:
- an antenna feed to input a cylindrical feed wave;
- and
- a physical antenna aperture coupled to the antenna feed and comprising a plurality of segments having antenna elements that form a plurality of closed concentric rings of antenna elements when combined, the plurality of concentric rings being concentric with respect to the antenna feed.
A flat panel antenna comprising:
- an antenna feed to input a cylindrical feed wave;
- a physical antenna aperture coupled to the antenna feed and comprising a plurality of segments having antenna elements that form an array with a plurality of closed concentric rings of antenna elements when combined, the plurality of concentric rings being concentric with respect to the antenna feed, wherein combining the plurality of segments results in an open area centrally located at which the antenna feed is located;
- and
- a controller to control each antenna element of the array separately using matrix drive circuitry, each of the antenna elements being uniquely addressed by the matrix drive circuitry.
