| 摘 要： | 设计了一种ETC用低旁瓣圆极化微带阵列天线,应用于电子收费(ETC)的路测单元(RSU)。为实现低旁瓣、圆极化的效果,对2个微带天线单元运用旋转与相位补偿的方法进行轴比改进,并以改进后的2单元作为辐射单元制作了一款基于道尔夫-切比雪夫幅度分布的微带天线阵列。经过仿真与实际测量,该天线具有很好的低旁瓣、圆极化的效果。该天线对于ETC系统以及其他类似的天线系统具有很好的理论与实际意义。

| Abstract: | A low-sidelobe circularly-polarized microstrip array antenna used in road side unit(RSU) for electronic toll collection(ETC) was designed.In order to achieve the effect of low-sidelobe circular polarization and low axial ratio,two microstrip antenna units was modified with the rotation and phase compensation methods to reduce axial ratio.The improved two units is taken as a radiative unit to make a microstrip antenna array,whose amplitude distribution is based on Dolph-Chebyshev.The simulation and measured results indicate that the antenna has the effect of low-sidelobe and circular polarization.The antenna system has a good theoretical and practical significance for ETC and other similar antenna systems. |
