TL;DR: In this article, a method to generate orbital angular momentum (OAM) radio waves based on dielectric resonator antenna is demonstrated, and an equivalent model is built to investigate this OAM antenna in detail.
Abstract: 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

TL;DR: In this paper, a dual-band omnidirectional cylindrical dielectric resonator antenna (DRA) using TM011 and TM012 modes is investigated, and the limit of frequency ratio is found, and formulas that determine the dimensions of the DRA from two given frequencies have been provided.
Abstract: Design of a dual-band omnidirectional cylindrical dielectric resonator antenna (DRA) using TM011 and TM012 modes is investigated in this letter. The limit of frequency ratio is found, and formulas that determine the dimensions of the DRA from two given frequencies have been provided. To verify the theory, a dual-band omnidirectional cylindrical DRA operating in 3.5-GHz WiMAX and 5.8-GHz WLAN bands is designed and tested. The reflection coefficient, radiation pattern, and antenna gain are studied, and reasonable agreement between measurement and theory is observed.
