摘要： The present invention relates to antenna architectures and methods on re-configurable multi-element antennas via feed re-positioning for various optimized radiation contours, including beam forming (or shaping) and/or null steering on contoured beams, spot beams, and orthogonal beams. The feed re-positioning techniques can also be used in radiation pattern optimization processing during antennas designing phases for fixed beams. The techniques are applicable for satellite communications. For satellite antennas, the beam shaping capability via element repositioning can be utilized for (1) optimized geometries on satellite antennas for given desired coverage areas, (2) re-optimizing radiation contours for reconfigurable antenna on board satellites in operation, (3) additional flexibility for satellite antennas using ground based beam forming (GBBF). As to satellite ground terminals, the same techniques are applicable for both fixed and mobile satellite terminals featuring either single beam or multiple beams. For fixed terminals, are applicable for terrestrial based communications; such as retrofitting existing antennas eliminating interference radiations coming from fixed or slow varying directions.
