摘要
提出一种分析阵列天线辐射方向图的阵列扩展方法。该方法在计算阵列天线辐射方向图时,只计入较邻近单元的互耦效应,忽略较远单元之间的互耦,从而简化了计算方法、加快了计算速度。以Vivaldi阵列天线为例,应用阵元扩展方法对其辐射方向图进行仿真计算,仿真结果和测试结果吻合,主瓣完全一致,副瓣基本一致。该阵元扩展方法可以应用在阵列天线辐射预测与仿真工作中。
Array element extension method is presented in this paper. When this method is adaopted to calculate the radiation patterns, just the mutual coupling of the adjacent elements is computed and the mutual coupling of the remote elements is ignored, which simplified the calculation and accelerateed the computation. Taking the Vivaldi array antenna as an example, array element extension method is applied to calculate its radiation patterns. The studies showed that the simulation and measured results were anastomotic, completely consistent in the in the main lobe and basically consistent in the side lobes. The proposed array element extension method is effective and can be applied in the estimation and simulation of the radiation pattern of array antenna.
