Abstract: The need to constantly increase the capacity and efficiency of communication satellites has led to the advent and development of multibeam satellite antenna technology. In this paper, four major types of multibeam satellite antennas are reviewed: single offset reflector with feed array, shaped reflector system, active arraysand imaging reflector antenna. The review includes their structure, analytic methodand applied area. Examples of existing systems are also given.
