摘要
本文针对目前在智能交通领域受到高度关注的短程通信技术(DSRC:Dedicated Short Range Communications),提出一种用于DSRC的16单元微带天线阵列,其主要用于ETC、智能停车场等系统中的路侧单元(RSU:Road Side Unit);针对传统平面阵列天线圆极化轴比带宽窄的缺点,采用连续旋转馈电技术的方法来改善其轴比带宽,通过HFSS软件对设计方案进行电磁仿真,得到预期的结果。最后对样品测试发现其相对于传统阵列,轴比带宽提高了3倍以上。
In this paper,a 16-element microstrip antenna array for DSRC is proposed for DSRC(Dedicated Short Range Communications). It is mainly used in ETC,intelligent parking lot and other systems.(RSU: Road Side Unit). In order to improve the axial bandwidth of the conventional planar array antenna,the circular polarization axis is narrower than that of the conventional planar array antenna. The design scheme is simulated by HFSS software,To obtain the desired results. The results show that the axial bandwidth is more than 3 times higher than that of the conventional array.
