英文摘要	A KB-band beam-steering leaky-wave antenna (LWA) based on composite right/left-handed (CRLH) rectangular waveguide is proposed and investigated in this paper. The CRLH waveguide is composed of a traditional rectangular waveguide with short-circuited double ridge corrugations periodically mounted on one broadtail. The CRLH structure is air-filled to avoid dielectric loss. A straight long slot is cut on the other broadtail of the rectangular waveguide acting as the radiation aperture to realize a LWA. A balanced condition has been optimized for the LWA to acquire a continuous beam-steering capability from backward to forward quadrants. This capability is verified and high-gain performance is realized by simulations. Compared with other planar CRLH LWAs, the LWA proposed in this paper has the advantages of high power capacity, low loss and consistent high gain, which is very suitable for applications in practical radar systems.
