| 摘 要： | 提出了一种基于方向图可重构天线单元的新型相控阵，并分别研究了其均匀、非均匀相控阵的扫描特性。通过重构天线单元的工作状态和各单元的激励，其均匀阵可以获得低副瓣电平等较好的辐射性能，其非均匀阵的主波束扫描范围达到±80°，在扫描平面内3dB 主波束覆盖可达176°，且栅瓣电平很低。研究表明了重构天线在相控阵天线研究中
的广阔应用前景。

| Abstract: | A novel phased array is proposed based on pattern reconfigurable antenna element in this letter and thescanning characteristics of uniform and nonuniform phased arrays are studied. By shifting operating states and adjusting theexcitation of the elements, the uniform array can obtain a good radiation performance such as low side lobes, and thenonuniform array can scan its main beam from -80o to +80o with 3 dB beam coverage of 176o and with low side lobes. Thestudies indicate that the pattern reconfigurable antenna has a tremendous potential in phased array applications. |
