AbstractA circular time-switched array (TSA) is analysed and configured to radiate radio waves which correspond to the modes associated with orbital angular momentum (OAM) theory. Results are presented to show that the harmonic frequencies radiated by the circular TSA directly correspond to OAM modes of progressive order, including negative modes.
