Abstract: A radio frequency antenna array uses multiple lenses, and mechanically movable elements, to provide ground-based and sky-based coverage for multiple object communication and tracking. The antenna array includes at least two spherical lenses, where each spherical lens has at least two associated RF elements. A third lens is added, along with at least two additional RF elements to narrow and track the overlapped beams from the first and second lenses. Each lens also includes a sub-controller configured to adjust a phase of the signals 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 configure the phase shifter to modify a phase of the output signals from the elements based on the relative positions between the RF elements. The overlapped beams track independent targets, such as satellites, across an area.

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 a track around one or more spherical lenses and by placing lower band radiators between spherical lenses. By using secondary lenses for high band radiators, coupling between low band and high band radiators is reduced. Beam tilt range and side lobe suppression are improved through phase shifting and/or a rotational angle of radiators. A wide beam tilt range (0-40 degree) can be achieved via the proposed multi-beam antenna systems. Each beam can be independently tilted. Based on proposed single and multi-lens antenna solutions, cell coverage improvements and stadium tribune coverage optimization are also achieved, together with a reduction in interference.

Abstract: An antenna has multiple RF elements disposed about a lens in at least two tracks. The at least two tracks collectively subtend more than 360° about the lens, providing highly customizable, adaptable, and steerable wireless communication. An array of multiple lenses and tracks is also contemplated.

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.

Abstract: An antenna includes a stack of cylindrical lenses combined with feed elements to provide multi-beam coverage for a given wireless communication sector. Each cylindrical lens disc has approximately the same height as the feed elements being used with the lens. To overcome the problem of interference from cables and opposing feeds, feed elements are placed around the lens. The cylindrical lenses are stacked such that a small gap exists between each pair of adjacent cylindrical lenses, allowing for cable lines to pass through between the pair of the cylindrical lenses, and thus removing interference for 360 degree coverage. Cable lines are arranged such that they only traverse the portion of the circumferential surfaces of the cylindrical lenses that do not interfere with the field of view of the RF signals generated by the corresponding feed elements.
