A scientific paper regarding the design of high performance horn antennas for satellite communication applications, done in collaboration by the Public University of Navarra Antenna Research group and Anteral, was published in the April 2015 special issue on Antennas for Satellite Communications of the IEEE Transactions on Antennas and Propagation journal, one of the most prominent antenna related peer-reviewed journals.
The paper explains the difficulties of designing very large bandwidth horn antennas for satellite communication applications, and gives some guidelines for designing high performance compact horns with large bandwidth and multiband capabilities.
Abstract
Today, telecommunication satellite horn antennas are required to be wideband mainly because of the additional 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 now-a-days, with recent advances in orthomode junctions and transducers, they are usually the bandwidth limiting component of a satellite antenna as often low crosspolar level is the toughest specification parameter. In this paper, the design guidelines for horn antennas that combine horizontal and vertical corrugations are explained, the method to prepare a preliminary profile for optimization is shown, and an example of a satellite feedhorn with severe requirements is presented.
