Half-mode substrate integrated waveguide antenna for generating multiple orbital angular momentum modes

To multiplex multiple orbital angular momentum (OAM) beams, a compact half-mode substrate integrated waveguide leaky-wave antenna (LWA) for generating multiple high-order OAM modes is presented. The LWA is based on a cavity resonator with two feeds of ±90° phase difference. The principle and mode an...

Description
Summary:To multiplex multiple orbital angular momentum (OAM) beams, a compact half-mode substrate integrated waveguide leaky-wave antenna (LWA) for generating multiple high-order OAM modes is presented. The LWA is based on a cavity resonator with two feeds of ±90° phase difference. The principle and mode analysis of the resonator are discussed, and the generation of high-order OAM beams is proved by the measurements.
