| 摘 要： | 采用等效磁流分析方法，将波导激励的单背腔缝隙单元阵场求解问题离散，得到缝隙表面的边界积分方程。应用矩量法求解该边界积分方程，得到单背腔缝隙单元阵的场结构。再应用阵列天线理论仿真计算了一种易于共形的缝隙天线阵的方向图，与实际测量结果进行了对比，取得了较好的效果。

| Abstract: | This paper applies the method of equivalent magnetic current to make the field- solve problem of slot antenna which is backed by a single cavity and excited by a waveguide discrete, then it gets the boundary integral equations above the surfaces of the slots. Next uses the method of moment to solve the equations and gets the field structure of the particular antenna. Through using the theory of array antenna,it gets the directivity pattern of the slot array antenna. This directivity pattern is compared to the measured directivity pattern, and gets a nice result. |
