MULTI-BEAM ANTENNA Russian patent published in 2018 - IPC H01Q19/17 

FIELD: antenna technology.

SUBSTANCE: invention relates to telecommunication multi-beam antenna systems with a focal device consisting of a two-dimensional array of irradiators, in which a plurality of beams are simultaneously generated by setting the amplitude-time parameters of the signals for each illuminator. Multi-beam antenna, in which the focusing device in the form of amplifying lens (6) is irradiated by irradiating device (1), which is designed as two-dimensional array of irradiators (2). System of beam formation for each active beam forms, with the help of a certain subarray of irradiators, nonplanar wave front (5b) equidistant to plane wave front (5a) in a given beam direction. In this case, the radiating surface of the array of irradiators is outside self-intersection zone of nonplanar wave fronts (5d), and refractive surface (9) of the amplifying lens has a continuous second derivative. In this case, the refractive surface of the lens can be a surface of revolution, with an axis of rotation that does not coincide in angle and (or) position with the axes of the amplifying lens and (or) the irradiating device. In addition, the refractive surface can be formed by drawing one, in a generally variable, curve along the other guiding curve.

EFFECT: technical result consists in providing the possibility of obtaining a large number of active rays.
