Simulation, analysis and optimization of innovative high-efficiency multiple-beam spline-profiled antenna structures

Abstract

The following work deals with the design and optimization of five high-efficiency splineprofiled feedhorn antennas to be used aboard a future communications satellite as part of a multibeam reflector system. Design requirements are discussed, and the final profile and projected frequency performance for every antenna is provided along with insight into the process that led to each particular design. A background of the theory behind spline-walled horns, multiband and multibeam systems is also studied, as to provide a sufficient framework to understand the key concepts discussed in the main body of work. As a conclusion, important observations about the work are analyzed and possible lines of future investigation are explored.
