Abstract
This disclosure presents an orbital angular momentum (OAM) antenna that includes a plurality of concentric antenna arrays, each antenna array corresponding to a different respective OAM order and being comprised of a different respective set of antenna elements arranged at a different respective radius. The OAM antenna also includes a plurality of phase shifters, each phase shifter corresponding to a different respective antenna array of the plurality of concentric antenna arrays. Each phase shifter is configured to trigger the respective set of antenna elements of a corresponding antenna array to generate a respective OAM beam. According to aspects of the disclosure, each OAM beam generated by a respective antenna array has a same divergence angle as the other OAM beams generated by the other respective antenna arrays of the plurality of concentric antenna arrays.
