摘要：
A novel leaky-wave antenna (LWA) with wide bandwidth and high efficiency based on dielectric ridged parallel-plate waveguide (DRPW) is proposed. The DRPW is constructed by placing a dielectric ridge into the parallel-plate waveguide, which combines both the wideband property of the parallel-plate waveguide and the field confining effect of dielectric ridge. The zero cutoff frequency of DRPW and flexible path design of radiation aperture make it an excellent fundamental waveguide for broadband LWA design. Based on DRPW, an LWA with extraordinary radiation performance is proposed, which achieves a single-beam operating bandwidth of 55.4%, and the simulated total in-band efficiency is over 92%. The antenna can realize a back-to-front scanning range of 67 degrees. The simple structure, low profile and high radiation performance make it a good candidate for wireless communication and detection in millimeter-wave applications.
