摘要：

A novel kind of high-efficient leaky-wave antenna array based on substrate integrated waveguide is investigated for sidelobe suppression and multibeam generation. The antenna array is designed upon a previous work with two feeding ports, and a tapered radiating slot array introduced. This kind of structure enables the array to have not only the compact architecture and high efficiency, but also the multibeam radiation and low sidelobe level (SLL). Different beams are generated by feeding the array from different input ports, and the SLL is reduced by the tapered slot lengths. The array was fabricated and measured, and the results are consistent with that of simulation.
