Provided are an orbital angular momentum (OAM)-based transmitter, receiver, and communication method employing a radial concentric uniform circular array (UCA). The OAM-based communication method includes transmitting, by a transmitter, OAM multimode signals through a UCA-based transmitting antenna and receiving, by a receiver, the OAM multimode signals through a radial concentric UCA structure antenna including a plurality of UCA antennas. The plurality of UCA antennas each have the same number of antenna elements, and antenna elements having the same sequence number in the plurality of UCA antennas are on the same radial line in the radial concentric UCA structure antenna.

Orbital angular momentum-based transmitter, receiver, and communication method

A massive antenna-based pattern/polarization beam division multiple access method and an apparatus performing the same are provided. The massive antenna-based pattern/polarization beam division multiple access method includes generating a plurality of beam sectors for each antenna array by using a plurality of pattern/polarization antenna arrays and performing MIMO transmission in each of the plurality of beam sectors, wherein the plurality of pattern/polarization antenna arrays each have a different radiation pattern.
