Abstract
A phased array antenna system for eliminating antenna induced errors and distortions comprising an antenna array consisting of orthogonal rows and columns of antenna elements in which each row of elements is supplied signal power by a single beam forming network. Each input port of the beam forming network corresponds to an element of only one of a number of composite beam constituents which, when combined, form the complete composite beam. The beam constituents are adjusted in position to correct the composite beam shape as necessary by means of plurality of phase shifters, each of which is placed in series with only one input port of the beam forming networks. This unique positioning of the phase shifters in the antenna distribution system reduces the total number of phase shifters required to control the beam, permits the forming of a shaped beam such as a fan beam without the need for amplitude control and simplifies the complexity of the phased array control system.
