摘要

用有限元法计算了毫米波相控阵中代表性边缘位置的场分布和远场方向图。同时，采用分解-求解-重构(DSR)方法分别合成了两个尺度阵列扫描中不同外缘环的边缘效应。典型平面上的扫描方向图和波束宽度表明，边缘元素的贡献会随着天线阵列尺度的变化而变化。因此，在中小规模天线阵的方向图合成中应考虑边缘效应。

Effects of edge elements on the scanning character analysis of millimetre wave phased antenna array

The field distributions and far-field patterns of representative edge positions in millimetre wave phased antenna array have been calculated with the Finite Element Method (FEM). Simultaneously, the Decompose-Solve-Recompose (DSR) scheme is applied to synthesize the edge effects in different outer edge rings within two scale arrays scanning respectively. The scanning patterns and beamwidth in the typical planes demonstrate that the contributions of edge elements will be varied with the scale changing of antenna array. Therefore, edge effects should be considered in the pattern syntheses of small-scale and medium-scale antenna arrays.
