| 摘 要： | 基于电调复合左右手传输线相移器，提出了一种新型相控阵天线波束控制方式：通过电压控制相移器的相移，从而使相控阵天线中心频率工作在边射方向，并允许向边射外的两个方向进行扫描。作为实例，设计制造了一个应用在ISM波段的平面串联馈电贴片相控阵天线，并对其进行了测试。结果表明：该相控阵天线可实现连续扫描，边射方向波束倾斜小(2°...

| Abstract: | Based on the tunable composite right/left-handed transmission line phase shifter,a novel beam steering method for phased array antenna was propounded.That was,through controlling the phase shift of phase shifter by changing voltage,the center frequency of phased array antenna was capable of working in the broadside direction and allowed to scan in both directions off the broadside.A planar serially fed patch phased array antenna working in the ISM band was designed,fabricated and characterized.The results s... |
