摘要

本文介绍了一种在周期性调制微带上具有水平扫描波束和宽边辐射的漏波天线。水平辐射是通过在地平面上周期性蚀刻一组谐振开口槽来实现的。首先分析了频散图和布洛赫阻抗，以研究周期性结构的传播和辐射特性。随后，安装并联匹配存根，以获得通过宽边的无缝光束扫描特性。最后，我们制作了一个原型来验证所提出的天线。仿真和测量结果完全一致，表明消除了开阻带效应和水平辐射波束。制作的天线波束范围为 -62° 至 +34°，在 10 GHz 频率下的最大测量增益约为 14.6 dBi。

A Microstrip Leaky-Wave Antenna with Scanning Beams Horizontal to the Antenna Plane

A leaky-wave antenna with horizontal scanning beams and broadside radiation is presented on the periodically modulated microstrip. The horizontal radiation is realized by periodically etching a set of resonant open-ended slots on the ground plane. Dispersion diagrams and Bloch impedance are first analyzed to investigate the propagation and radiation characteristics of the periodic structure. Subsequently, shunt matching stubs are installed aiming to obtain seamless beam scanning property through the broadside. Finally, a prototype is implemented as verification of the presented antenna. Results of the simulations and measurements agree well with each other, indicating the elimination of the open-stop band effect and the horizontal radiation beams. The fabricated antenna exhibits a beam range from -62° to +34°, and provides a maximum measured gain about 14.6 dBi at 10 GHz.
