本文提出了一种用于76 GHz汽车雷达系统的低副瓣单层波导缝隙天线阵。π-结阵列和缝隙阵列的设计都是为了实现二维泰勒分布。旁瓣电平的目标是-25dB。在E-和H-平面上的测量证实了旁瓣低于-24 dB的良好辐射方向图。保持了不低于34.5dBi和50%的高增益和高效率。
This paper presents a low sidelobe single-layer slotted waveguide array for car radar systems at the 76 GHz band. Both the array of the /spl pi/-junctions and that of the slot array are designed to realize the two-dimensional Taylor distribution. A target for the side-lobe level is -25 dB. Good radiation patterns with side-lobes below -24 dB are confirmed by the measurements in both E- and H-plane. High-gain and high efficiency of no lower than 34.5 dBi and 50% are preserved.
