Composite right/left-handed (CRLH) waveguide leaky-wave antenna (LWA) with low sidelobe level (SLL) and high radiation efficiency is investigated and designed in this paper. Due to the characteristic of negative and positive dominant mode propagation constant of the CRLH transmission line. a backward to forward beam-steering LWA can be realized through frequency scanning. The leaky-wa... https://www.ensemblecarpediem.com/product-category/scene-setters/
