Abstract
A system for correcting for dispersion in a beam radiated by a flat microwave antenna due to variations in the frequency of operation by providing an electronically controlled phase shift of the beam in the plane of the dispersion. The methods consist of combining with the flat antenna a matrix of particular wire conductors of which certain are controlled such that the phase shift introduced by the matrix is able to correct for the dispersion of the flat antenna.
