摘要

提出了一种基于介质脊状平行板波导（DRPW）的宽带高效漏波天线。通过在平行板波导中放置一个介质脊来构建DRPW，它结合了平行板波导的宽带特性和介质脊的场约束效应。DRPW的零截止频率和辐射孔径的柔性路径设计使其成为宽带LWA设计的优良基波导。基于DRPW，提出了一种具有优异辐射性能的LWA，实现了55.4%的单波束工作带宽，模拟总带内效率超过92%。该天线可实现67°的前后扫描范围。其结构简单、外形小巧、辐射性能高，是毫米波无线通信和探测的理想选择。

A Broadband Leaky-Wave Antenna With High Efficiency Based on Dielectric Ridged Parallel-Plate Waveguide

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°. The simple structure, low profile and high radiation performance make it a good candidate for wireless communication and detection in millimeter-wave applications.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
