摘　　要：提出了一种新结构形式的宽带宽角扫描天线单元,对其监测耦合线与天线单元进行了一体化设计。该结构形式可以保证相控阵天线系统中监测系统的稳定性。所设计出来的相控阵天线单元相对带宽超过25%,能够实现二维±60°的宽角扫描。单元上集成设计的耦合线,其各个端口间的耦合系数一致性很好,同时带内起伏也比较平坦。A novel phase array antenna with integrated designed couple line is designed and measured in this paper. This kind of structure assures the stability of monitor system of active phased array radar. The relative frequency band is larger than 25 %. The phased antenna array can electrical scan 60 degree both in E-plane and H-plane. The couple coefficient between the ports of different antenna elements in 8-ele structure and the couple port of couple line are in good consistence. Curve of the couple coefficient in the whole frequency band is flat.
