摘　　要：非对称单脊波导裂缝线源是一种新型相控阵天线辐射单元。由该种单元垂直放置构成的平面相控阵天线在水平面可实现宽角(±60°)扫描,在波束扫描时,还可以避免寄生副瓣的出现。同时,该种单元本身在垂直面易于实现较低的副瓣电平。本文从理论和实验上对非对称单脊波导裂缝阵天线进行了研究,解决了线源设计过程中的基本理论和关键技术。十六单元样品线源远场实验结果与理论值的一致性说明了本文的理论分析和实现途径是正确有效的。Asymmetric ridge waveguide slot array is a novel linear array radiating element for phased array antenna. The phased array can scan to wide angle(±60°)in azimuth,and can eliminate secondary beams when beam is scanning,which consists of many vertical asymmetric ridge waveguide slot linear array elements. And at same time,the linear array can easily obtain low side-lobe. The theoretical and experimental study for the linear array is performed in this paper. The basic theory and key technique for the linear array are resolved during the design procedure. A sixteen-slot constructed array is tested at far field. The agreement of experimental results with the theory validates that the theoretical analysis and the design proceduce for collinear slot array of asymmetric ridge waveguide are correct and effective.
