| 摘 要： | 辐射单元矩形栅格排列是相控阵天线中最简单的排列方式,也是最常用的一种排列方式。它是把整个阵面划分成许多矩形栅格,每个辐射元占据一个自然格或栅格的交点。而本文对子阵模块间采用三角形栅格而子阵模块内采用矩形栅格的排列方式进行了分析,通过理论分析验证这种排列方式比普通矩形栅格排列有较大优势。

| Abstract: | Radiation elements arranged in rectangular grids is the simplest and commonly used arrangement of phased array antennas; in this way, the antenna surface is divided into many rectangular grids, and each radiation element is located in a grid or at an intersection of grids. A new subarray arrangement method, that is, the radiation elements belong to a same subarray module are arranged in a rectangular grid, while subarray modules are further arranged in triangular grids, is analyzed. Theoretical analysis to this arrangement method verified that this method has many advantages compared to rectangular grids used commonly. |
