Satellite horn antennas design

Telecommunication satellite horn antennas require now-a-days more and more stringent requirements based mainly in the increased bandwidth necessary to accommodate more transponders to increase the capacity of the new satellite services. In this aspect horn antennas play a key role in the development of wider bandwidth services on board satellites because they are usually the reason that limits bandwidth in a satellite antenna. In this paper a brief review of design method and performance for Amazonas-2 telecommunication satellite horn antennas designed by the Antenna Group of the Public University of Navarra will be presented.
