一种新颖的微带多波束阵列天线将波束合成与阵列功能结合在单个基片上。一个具有5波束6×7元的天线阵,对其辐射特性的首次分析验证了原理的合理性。本文有两点重要进步。首先,最初的平面阵列变成了柱面阵列形式,它可允许多波束覆盖超过360°的扇面,实验结果已证实了这一点。其次,对天线阵进行了更具体的分析,包括在阵列中通过可能的多个通道之间耦合,这在原理上可用于柱面天线阵,对平面阵则具有独特应用;同时,本文给出一些结论。
A novel microstrip multibeam array antenna combines beamforming and array functions on a single substrate. An antenna array with 5 beams of 6 × 7 elements, the first analysis of its radiation characteristics verify the rationality of the principle. This article has two important progress. First, the original planar array became a cylindrical array that allowed multiple beams to cover sectors over 360 °, as demonstrated by experimental results. Secondly, more detailed analysis of the antenna array, including the possible coupling between multiple channels in an array, which is theoretically applicable to a cylindrical antenna array and a unique application to a planar array is given. In the meantime, Some conclusions.
