SYSTEMS AND METHODS FOR FOCUSING BEAMS WITH MODE DIVISION MULTIPLEXING

摘要

A system for focusing a multiplexed beam includes OAM signal processing circuitry for generating a multiplexed OAM multiplexed signal. A plurality of antennas comprises an antenna array. An antenna array control circuit controls transmission of the multiplexed OAM signal from each of the plurality of antennas in the antenna array. The antenna array control circuit generates control signals to cause the antenna array to transmit the OAM multiplexed signal from each of the plurality of antennas of the antenna array toward a focus point as a transmission beam and controls a timing of the transmissions of the OAM multiplexed signal from each of the plurality of antennas of the antenna array to cause the transmitted OAM multiplexed signals to arrive at the focus point at substantially a same time.
