Simulation and Experiment Results of the Generation of One OAM Beam.
(a) The intensity profile of the OAM + 1 beam generated from an array of 8 antenna elements at 1.2 m. (b) The interference pattern of the generated OAM + 1 beam with a Gaussian beam. (c1-c5) The intensity profiles of OAM + 1 beams generated from 8 antennas at 0.4 m, 0.6 m, 0.8 m, 1.0 m and 1.2 m, respectively.
