Abstract:
1. A reflector array comprising a plurality of individual radiating elements arranged alongside one another and forming a reflecting surface capable of reflecting incident waves with a phase variation law selected to provide a given coverage, wherein: the individual radiating elements are produced using planar technology, each radiating element of the reflecting surface is selected from a set of predetermined consecutive radiating elements, being a pattern, the pattern being capable of creating a progressive phase variation corresponding to a 360° phase cycle between a first element and a last element of the pattern, the 360° phase cycle consists of two successive different, first and second, phase ranges, and the pattern comprises several consecutive first radiating elements having a radiating structure of metal patch type in which the size of the metal patch increases progressively from one radiating element to another adjacent radiating element to obtain a first range of progressive phase variation corresponding to the first phase range of the 360° cycle and several consecutive second radiating elements having a radiating structure of aperture type in which the size of the aperture increases progressively from one radiating element to another adjacent radiating element to obtain a second range of progressive phase variation corresponding to the second phase range of the 360° phase cycle.
