摘要

An Antenna structure in phases, the Antenna provides coverage over a geographic region and provides a Plurality of Predefined do within that region.And includes: a Plurality of antenna elements (20),Each Antenna element has a Signal Antenna element has a phase and amplitude relationship with other signals of the elementAnd the antenna elements are divided into a Plurality of overlapping substructures (24),Each substructure comprises a subset of all the elements of the Antenna structure in phases, and at least some of the antenna elements are involved in more than one substructureA Beam Forming Network (25) in the substructure that assigned to the respective elements of each substructure of Beamforming weights in the substructureA Beam Forming Network and main Beam Forming Weights assigned each substructure to each of the Plurality of beamsTo produce such a Plurality of beams within the region wherein the Beamforming Weights assigned to each substructure in the substructure have been optimized TorqueTo achieve a desired level of this directionality for the Plurality of beams through an Optimization Process where the Beamforming weights in the substructure Change dE value iterations, and each iteration is determined by the values of Beamforming Weights assigned to each substructure.
