Abstract
A plurality of antenna elements in a phased array are arranged to be supplied in serial fashion by means of couplings spaced along a distribution system. A plurality of phase shifters are placed in series within the distribution system with one shifter being located prior to each coupling to control the phase supplied to the elements and thereby control the direction of the radiated beam. Samples of the signal to be transmitted are taken at the input and output of the distribution system and compared to determine the total phase shift through the system. The total phase shift is then compared to a desired total phase shift to generate an error signal which is applied to the phase shifters to produce the total desired phase shift and thus accurately steer the beam to a desired spatial angle.
