Аннотация
The antenna comprises main and sub reflectors, each of which being made with nonaxisymmetric curvilinear surfaces and having two planes of symmetry at the intersection. A feed is arranged between the main and sub reflectors and capable of illuminating, first, the sub-reflector and, through it, the main reflector to form plane wave front. The common focuses of the nonaxisymmetric curvilinear surfaces of the reflectors in all sections passing through the longitudinal axis Z of the antenna, is located at the portion Z0 of Z, wherein the length of said portion being restricted by limits Fmin≦Z0≦Fmax, where Fmin, Fmax are the minimum and maximum distances from the ends of the portion Z0 to the main reflector along Z. The length of Z0 satisfies the following relation; Fmin/Dmax≦Zo/Dmax≦Fmax/Dmax and 0.21≦Zo/Dmax≦0.47, 1>Dmin/Dmax>0.5, where Dmax and Dmin are the maximum and minimum transverse sizes of the main reflector aperture.
