Abstract
A reflector array comprises a plurality of individual radiating elements forming a reflecting surface with no abrupt transitions wherein each radiating element of the reflecting surface is selected from a set of predetermined consecutive radiating elements, called the pattern, the first and last elements of the pattern correspond to one and the same phase, modulo 360°, and are identical, and the radiating elements of the pattern have a radiating structure, of metal patch type and/or of radiating aperture type, that progressively changes from one radiating element to another adjacent radiating element, the change in the radiating structure comprising a succession of progressive growths of at least one metal patch and/or at least one aperture and appearances of at least one metal patch in an aperture and/or at least one aperture in a metal patch.
