Abstract :
The authors describe how a 265-beam MBA (multibeam antenna) may be used to emulate the performance of a 37-beam MBA. A study of the gain characteristics of a cluster of beams of a 265-beam MBA is performed, and a comparison is made with the gain of a single beam of a 37-beam MBA. It is shown that the composite beam formed by thirteen beams of a 265-beam MBA will provide better gain and coverage characteristics than that of a single beam of a 37-beam MBA
