摘要

给出了二维偶极子天线阵阻抗综合问题的解析解。该阵列由薄阻抗电偶极子组成，其中心位于具有双周期性的平面矩形网格的节点上。阵列中每个偶极子的辐射模式与孤立偶极子的辐射模式没有区别。提出了一种结合偶极子激发电流相位和表面阻抗同步变化的阵列辐射方向图广角扫描新方法。

Combined Wide-Angle Scanning by a Two-Dimensional Dipole Array

An analytical solution of an impedance synthesis problem for a two-dimensional dipole antenna array is obtained. The array consists of thin impedance electric dipoles whose centers are located at nodes of a planar rectangular grid with double periodicity. Radiation patterns of each dipole in the array does not differ from that of an isolated dipole. A new method for wide-angle scanning of the array radiation pattern, combining the simultaneous variation of phases of the excitation currents in the dipoles and of their surface impedances is proposed.
