A method to generate orbital angular momentum (OAM) radio waves based on dielectric resonator antenna is demonstrated. An equivalent model is built to investigate this OAM antenna in detail. Simulation and measurement are also carried out for this antenna. Both simulated and measurement results show typical and efficient radiation of OAM-carrying radio waves. It can generate radio waves with different OAM mode numbers at different frequencies. Because of its compact structure, low cost, and small size, this antenna will be a cost-effective solution for OAM wave generation
