摘要
将Elliott关于矩形波导裂缝阵理论推广运用到非对称单脊波导裂缝阵天线上,在考虑了裂缝外部互耦影响的情况下,给出相应的两个设计方程,同时给出8单元谐振裂缝线阵的具体计算和设计方法。加工样品的近场和远场测试结果证明了本文理论和设计方法是正确有效的。
In the paper,Elliott’s design theory for rectangular waveguide slot array is extended to slot array fed by asymmetric single-ridge waveguide. Considering external mutual coupling between the slots, two design equations are developed. And at the same time,the design procedure and evaluation for an eight-slot array are presented. The eight-slot array is tested under the farfield and the nearfield.and the results prove that the theory and the design procedure are correct and effective.
