| 摘 要： | 计算了一个平面上八元相控矩形微带贴片直线阵的辐射方向图和扫描时输入阻抗的变化．由于天线的工作波长运大于天线基片介质层的厚度，所以对电参数的计算采用传输线模型来处理．在计算天线阵中阵元间互耦时，我们利用了简化处理的并矢格林函数，根据反应原理，推导出了相应的计算公式，最后给出了数值计算结果，与实验取得了很好的一致．

| 关 键 词： | 微带天线，相控微带天线阵，并矢格林函数 |

| Abstract: | This papeer presents a computed method of radiation characteristic and inputimpedance for eight-elements microstrip phased linear array antenna on a plan. Becauseworking wavelength of the antenna is many more than thickness of substrate, so microstriptransmission lines modeling can be adopted to compute performance parameter for microstriparray antenna. In order to compute mutual coupling between antenna's elements, we use areduced dyadic Green's function. On the basis of response principle, we have deduced the expression for computating input admittance and radiation patten. Calculated results are presented and compared with those available by experiment. It is found that agreement is good. |
