The first, second and third antenna beams point in different directions.

Abstract: A communication system includes an array of RF elements that transit and/or receive signals through a lens, and a power divider is configured to provide unequal amplitude and/or phase to at least some of the RF elements. In transmit mode, the shape and direction of the resulting beam is controlled in part by the shape of the array, the relative power distributed to the different RF elements, the operating frequency, the shape of the lens, the position of the lens with respect to the array, and the distance of the lens from the array.

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: 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: One or more anisotropic lenses, where the permittivity and/or permeability is directional, are used to vary one or more of beamwidth, beam direction, polarization, and other parameters for one or more antennas. 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.
