摘要： 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.

摘要： 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.

摘要： A multi-level antenna array includes a plurality of patch antennas. Each layer of a plurality of layers is separated from other layers by a distance and support a portion of the plurality of patch antennas. Each of a plurality of connectors is associated with one of the plurality of layers for supplying a signal for transmission by the associated layer. A feed network on each of the plurality of layers provides a connection between a connector of the plurality of connectors associated with the layer and the portion of the plurality of patch antennas located on the layer. Each layer of the plurality of layers transmits the signal having a different orthogonal function applied thereto and multiplexes each of the signals having the different orthogonal function applied thereto onto a single transmission beam.
