This paper presents a circular leaky-wave antenna (CLWA) designed on a corrugated half-mode substrate integrated waveguide. The proposed CLWA is shown to generate an orbital angular momentum (OAM) beam of Mode 2 with frequency-controlled beam-scanning capability. The conventional straight LWA is converted into a compact CLWA with a continuous long slot to create a uniform leaky-wave architecture at 17.5 to 21 GHz. This architecture is used to generate continuous phase shift within a conical beam to generate Mode 2 OAM beam of high purity and efficiency with a frequency-controlled beam-scanning of ±35° in one plane.
