摘要

提出了一种新的多波束卫星通信天线重叠簇馈电阵列。该阵列由直径为1.1波长的圆波导组成。相邻元素通过凹槽被激发，从而形成重叠簇。优化了光团的激发，获得了平顶辐射模式和高孔径效率。该阵列可作为多波束天线的馈源。

Feed array with overlapping clusters and flat-topped radiation pattern for multi-beam satellite communication antennas

A new feed array with overlapping clusters for multi-beam satellite communication antennas is presented. The array consists of circular waveguides with diameter of 1.1 wavelength. Neighbor elements are excited via the slots and thus overlapping clusters are formed. Excitation of the clusters is optimized to obtain flat-topped radiation pattern and high aperture efficiency. The proposed array can be used as a feed for multi-beam antennas.
