Abstract: The multi-beam lens antenna contains a spherical centro-symmetric lens (1), fixed by means of joints (3) fastening it to a frame (2) in the form of an ellipse, so that the center of the lens (1) lies outside the plane of the frame (2). The frame (2) is installed on the base (4) and able to turn relative to the horizontal plane. The antenna also contains illuminators (8), positioned on the semi-circle guide (9), connected to the frame (2) by means of fastening joints (11). The joints (3, 11) fastening the lens (1) and the semi-circle guide (9) to the frame are constructed as self-positioning in their angle placement and adjustable with the possibility of moving along their axes.

Abstract: The spherical dielectric lens with variable refractive index contains modules (1, 4, 7, 9, 12) connected with one another and made from homogeneous dielectric materials with various .di-elect cons. values, which are arranged in accordance with the given principle of change in dielectric permittivity .di-elect cons. from the radius value (r) of the lens, uniquely corresponding to the rule of variation of its refractive index (n). The modules (1, 4, 7, 9, 12) of the interior layers, which form the central cubic core, are inscribed in a sphere, are of cubic form and are equal in size, while the exterior modules (1, 4, 7, 9, 12) have an outer surface of spherical form, where the latter interior layer modules (1, 4, 7, 9, 12) fill out the central core up to the sphere.
