Publication number: 20210266213Abstract: This application proposes multi-beam antenna systems using spherical lens are proposed, with high isolation between antenna ports and compatible to 2×2, 4×4, 8×8 MIMO transceivers. Several compact multi-band multi-beam solutions (with wideband operation, 40%+, in each band) are achieved by creating dual-band radiators movable on the track around spherical lens and by placing of lower band radiators between spherical lenses. By using of secondary lens for high band radiators, coupling between low band and high band radiators is reduced. Beam tilt range and side lobe suppression are improved by special selection of phase shift and rotational angle of radiators. Resultantly, a wide beam tilt range (0-40 degree) is realized in proposed multi-beam antenna systems. Each beam can be individually tilted. Based on proposed single- and multi-lens antenna solutions, cell coverage improvements and stadium tribune coverage optimization are also achieved, together with interference reduction.Type: ApplicationFiled: May 6, 2021Publication date: August 26, 2021Inventors: Serquei Matitsine, Igor Timofeev, Leonid Matytsine, Anthony DeMarco

Patent number: 11050157Abstract: A radio frequency antenna array uses lenses and RF elements, to provide ground-based and sky-based coverage for multiple object communication and tracking. The antenna array can include two spherical lenses, where each spherical lens has at least two associated RF elements. Each of the RF elements associated with a given lens produces an output beam with an output area. Each lens also includes a sub-controller configured to combine the output beams produced by the RF elements. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically combine, or modify the phase of, the output beams from the RF elements based on the relative positions between the RF elements. The combined beams track independent targets, such as satellites, across an area.Type: GrantFiled: October 30, 2020Date of Patent: June 29, 2021Assignee: Matsing, Inc.Inventors: Serguei Matitsine, Igor Timofeev, Leonid Matytsine

Patent number: 10923804Abstract: An exemplary antenna system has first and second antenna elements, where a diplexer is connected to each second element. First phase shifters are connected to the first elements and to the diplexers, and second phase shifters are connected to the diplexers, but not to the first elements. Either a different bandpass filter is connected to the first and second phase shifters or a single multiplexer is connected to all phase shifters. The antenna system can be used to support communications over first and second sub-bands with independent beam tilts and equivalent beamwidths, where all of the elements are used for the first sub-band, and the second elements, but not the first elements, are used for the second sub-band. Each first element is separated from an adjacent element by a first distance, and each second element is separated from an adjacent element by a second distance different from the first distance.Type: GrantFiled: March 25, 2019Date of Patent: February 16, 2021Assignee: CommScope Technologies LLCInventors: Giuseppe Resnati, Igor Timofeev
