摘要

提出了一种可重构的77 GHz扇形波束天线，用于汽车雷达系统。所提出的天线阵列由三个偶极子和三个开路作为开关组成。因此，该天线可以通过控制开关状态实现三种可重构波束。介绍了设计过程，并对结构进行了优化和仿真。根据仿真结果，可选择全局匹配带宽为[75 ~ 81 GHz] (S11< 10 dB)的7种模式，峰值增益为6.18 dBi，总效率为78%。波束导向的方向模式(覆盖180°)可以根据工作状态进行电子调谐。与其他先进天线的比较表明，所提出的可重构阵列具有体积小、高增益和易于设计的特点。该天线适用于77 GHz汽车雷达系统。

Sector-Beam Antenna Array for 77 GHz Automotive RADAR Systems

This paper presents a reconfigurable sector-beam antenna that operates at 77 GHz for automotive RADAR systems. The proposed antenna array is composed of three dipoles with three open circuits used as switches. Therefore, the proposed antenna can achieve three reconfigurable beams by controlling the switches states. The design processes are presented, and the structure is optimized and simulated. According to the simulated results, seven modes with a global matching bandwidth of [75–81 GHz] (S11< 10 dB) can be selected with peak gain of 6.18 dBi and good total efficiency of 78%. beam-steered directional patterns (covering 180 °) can be electronically tuned depending on the working states. The comparison to other state-of-the-art antennas shows that the proposed reconfigurable array has a compact size, high gain and easy to design. This proposed antenna is well suitable for 77 GHz automotive RADAR systems.
