Abstract
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.
