Abstract
A method and apparatus for redistributing power radiated by an antenna comprised of a plurality of antenna elements. An antenna directivity estimator function is performed to screen out inappropriate antenna directivity profiles from a plurality of antenna directivity profiles, thereby determining one or more remaining, appropriate antenna directivity profiles. An optimizer function is performed on the remaining, appropriate antenna element directivities to determine a phase distribution for the antenna elements based on a desired power distribution for the antenna.

A method of redistributing power radiated by an antenna comprised of a plurality of antenna elements, the method comprising:
- (a) performing an antenna directivity estimator function to screen out inappropriate antenna directivity profiles from a plurality of antenna directivity profiles, thereby determining one or more remaining, appropriate antenna directivity profiles, wherein each of the antenna directivity profiles is represented as a set of Point Set Array (PSA) points over a coverage area, and each of the PSA points is assigned a desired directivity;
- and
- (b) performing an optimizer function on the remaining, appropriate antenna element directivities to determine a phase distribution for the antenna elements based on a desired power distribution for the antenna.
