Abstract
Antenna system and methodology for producing multiple interleaved beams using a hybrid frequency-reuse scheme. In particular, depending on the traffic demand in specific coverage areas, some beams are assigned with frequency channels in accordance with a 4-cell frequency-reuse scheme, and the other beams are assigned with frequency channels in accordance with a 7-cell frequency-reuse scheme. The antenna system has multiple feeds divided into clusters, and a number of reflectors fed by respective feed clusters and configured to form one beam for each of the feeds.
