RELECTOR WITH A SHAPED SURFACE AND SPATIALLY SEPARATED FOCI FOR ILLUMINATING IDENTICAL AREAS: ANTENNA SYSTEM AND METHOD FOR SURFACE DETERMINATION

摘要

The invention relates to a reflector with a shaped surface for electromagnetic waves, with the local shape of the reflector (1) being configured such that the reflector (1) comprises several spatially-separated foci (10a, 10b, 110a, 110b). In this way, electromagnetic beams of rays (5a, 5b, 50a, 50b) emanating from spatially separated radiators (4a, 4b, 40a, 40b), in particular beams of rays of different frequencies or different frequency bands, which illuminate the reflector (1), can be directed to a common illumination area (3, 3a, 3b).
