摘要

我们在这里介绍的工作包括验证用于汽车雷达的波束扫描概念。设计了一个2.45 GHz天线作为演示。其原理是基于Yagi-Uda天线，具有一个馈电单极子和两个负载寄生天线。然后，通过适当切换寄生负载来实现独特的波束扫描。给出了概念、仿真甚至实验结果，并证明了实现360°波束扫描天线的能力。与透镜解决方案相比，这种简单的结构提供了易于制造的优势，并且可以潜在地满足毫米波频率的防撞雷达规格。

A 360° beam switching monopole antenna for automotive radar

Our works presented here consisted in validate a concept of beam scanning used for automotive radar. A 2.45 GHz antenna, used as demonstrator, was designed. The principle is based on Yagi-Uda antennas, with a fed monopole and two loaded parasitic ones. Then, beam scanning is accomplished uniquely by properly switching parasitic loads. Concept, simulations and even experimental results are provided, and demonstrate the ability to achieve a 360° beam scanning antenna. This simple structure offers the advantage of easy manufacturing compared to lens solution, and can potentially meet specifications for collision avoidance radar in millimeter-wave frequencies.
