Abstract: A communications system receives a plurality of input data streams and applies a different orthogonal function to each of the plurality of input data streams. The system processes each of the plurality of input data streams to spatially locate a first group of the plurality of input data streams onto a first carrier signal and to spatially locate a second group of the plurality of input data streams onto a second carrier signal. The system temporally locates the first carrier signal and the second carrier signal onto a third carrier signal and transmits the third carrier signal over a communications link.

Abstract: A system for focusing an orbital angular momentum (OAM) multiplexed beam comprising OAM signal processing circuitry for generating an OAM multiplexed signal. The OAM multiplexed signal includes a plurality of data streams each having a unique orbital angular momentum applied thereto and multiplexed together within the OAM multiplexed signal. Each unique orbital angular momentum has a beam helicity value greater than l=2. An antenna array control circuit controls transmission of the multiplexed OAM signal from each of a plurality of antennas in an antenna array toward a focus point located below the ground as a transmission beam to cause the transmitted OAM multiplexed signals to converge at the focus point below the ground at substantially a same time to overcome a divergence of the transmitted plurality of OAM multiplexed signals caused by the beam helicity value of greater than l=2 for each of the unique orbital angular momentum.

Abstract: 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.

Abstract: A system and method for focusing an orthogonal function multiplexed beam receives an orthogonal function multiplexed signal from a data processing source. The orthogonal function multiplexed signal includes a plurality of data streams each having a unique orthogonal function applied thereto and multiplexed together within the orthogonal function multiplexed signal. The orthogonal function multiplexed signal passes through a pair of focusing lenses to focus the orthogonal function multiplexed signal on a predetermined focused point. A distance between the pair of focusing lenses is controlled to cause the orthogonal function multiplexed signal to focus at the predetermined focus point. The orthogonal function multiplexed signals are transmitted from a transmitter toward the focus point at a receiver aperture of a receiver as a transmission beam.
