Abstract: A radio frequency antenna array uses lenses and RF elements, to provide ground-based coverage for cellular communication. 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 is positioned with the other lenses in a staggered arrangement. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically phase compensate the output beams produced by the RF elements based on the relative distance between the RF elements.

Abstract: A multi-beam communication system uses an array of antenna assemblies, and RF elements, to provide two or more sets of multiple beams, where each individual set of beams can be considered a beam state. An antenna assembly has a first set of RF elements oriented to produce a first beam state, and a second set of RF elements oriented to produce a second beam state. Each set of RF elements comprise a set of output sectors, where a controller is configured to selectively activate a beam state.

Abstract: This application proposes multi-beam antenna systems using spherical lens 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.

Abstract: A lensed antenna system is provided. The lensed antenna system include a first column of radiating elements having a first longitudinal axis and a first azimuth single, and, optionally, a second column of radiating elements having a second longitudinal axis and a second azimuth angle, and a radio frequency lens. The radio frequency lens has a third longitudinal axis. The radio frequency lens is disposed such that the longitudinal axes of the first and second columns of radiating elements are aligned with the longitudinal axis of the radio frequency lens, and such that the azimuth angels of the beams produced by the columns of radiating elements are directed at the radio frequency lens. The multiple beam antenna system further includes a radome housing the columns of radiating elements and the radio frequency lens. There may be more or fewer than two columns of radiating elements.

Abstract: A plurality of directional antennas are arranged between an inner barrier (e.g., ring, wall, fence, glass, etc encircling a field, court, rink, stage, etc) and an outer barrier (e.g., guardrail, wall, etc encircling a seating region, etc) of the venue. Each directional antenna produces a beam pattern that is oriented such that the beam pattern is directed at an angle off-normal from the inner or outer barrier. Further, at least some of the directional antennas are placed at the openings of pedestrian tunnels leading into the seating region of the venue, near the inner barrier of the venue seating region, or placed near a midpoint between the inner and outer barriers so as to provide wireless communication services to users in the seating region of the venue.

Abstract: A lens elements array comprises at least two lens elements aligned along an alignment axis. Each lens element includes a spherical lens and a feed element. The feed elements are tilted such that the RF signals generated by the feed elements have major axes form an angle (preferably between 5° and 30°) other than a perpendicular angle with respect to the alignment axis. The combined RF signals produced collectively by these feed elements have amplitude that has minimal dips across the array. The feed elements that are farther away from the center of the array have higher levels of tilts than the feed elements that are closer to the center of the array.

Contemplated anisotropic lenses can include conductive or dielectric fibers or other particles. Lenses can be spherical, cylindrical or have other shapes depending on application, and can be rotated and/or positioned. Important applications include land and satellite communication, base station antennas.
