An antenna system for tracking multiple satellites comprises an RF lens (homogeneous or multiple layer Luneburg) with numerous feeds placed around the lens in a tightly packed arrangement to maintain high cross-over points between beams and high circularity. High-quality circular polarization, consisting of low axial ratio and low cross polarization levels, is maintained using a novel dielectric slab to compensate for the slight mismatch in phase delay through the lens from the two canonical polarizations vertical and horizontal. A weighted combination of beams is used to keep the resultant beam peak fixed on a satellite with the ability to use this approach in a number of places simultaneously, and simultaneously using one or more of these methods at multiple frequency bands.

Method of Adapting Wireless Network Beamforming to Antenna With Fixed Multiple Beams
Systems, methods, and devices are described for adapting multiple-element-array beamforming systems to work with passive multiple beam antennas, such as a RF lens. Such adaptations are implemented by hardware, by software, or combinations thereof. Hardware-based adaptations include introducing a reverse-beam-forming network in combination with traditional beam forming radios. Software-based adaptations include configuring a processor to interface with standard radio heads and an RF lens antenna to deliver beam-forming functionality. Codebook feedback is made compatible with lens beamforming without changing the user equipment, by modifying the CSI reference signals sent by the gNodeB to compensate for the unnecessary discrete Fourier transform operation.

A radio frequency antenna uses an array of spherical lens and mechanically movable radio frequency (RF) elements along the surface of the spherical lens to provide cellular coverage for a narrow geographical area. The antenna includes at least two spherical lens, where each spherical lens has at least one associated element assembly. Each element assembly has a track that curves along the contour of the exterior surface of the spherical lens and along which a radio frequency (RF) element can move. The antenna also includes a phase shifter 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.

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.
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.

Lens based antenna for super high capacity wireless communications systems
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.
