Abstract
A reflector antenna comprising a plurality of plane panels assembled edge to edge to form a non-plane surface constituting an approximation to a reference surface, and a beam-forming device generating a beam-forming function for an array of antenna elements coupled to said panels. The beam-forming function presents at least one surface error correction term to compensate at least in part for the difference between the surface constituted by the assembled panels and the reference surface. In a variant the manner for compensating for the error can be disposed on the panels.
