Abstract: This application proposes multi-beam antenna systems using spherical lens with high isolation between antenna ports and compatible to 2x2, 4x4, 8x8 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: The inventive subject matter provides apparatus, systems and methods in which a high port count base station antenna uses an array of spherical lenses with multiple ports per frequency band, containing multiple frequency bands, and capable of multiple beam operation. In a preferred embodiment, the antenna system comprises a plurality of spherical, dielectric lenses, stacked vertically, where each lens is surrounded by four or more lower frequency radiating elements, or one circular element. The circular element can have multiple sub-elements, along with feed gaps.

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.
