A dielectric corrugated feed horn antenna for satellite communication applications

In this study, a dielectric corrugated antenna, as being a feed horn antenna of the reflector antenna for satellite communication applications, is analyzed. The structure consists of a conical dielectric corrugated antenna terminated with a conductor hyperbolic (convex) plate. The antenna system provides a Gaussian beam within wide frequency bandwidth with its dielectric structure. The antenna is simulated and tested for its return loss and radiation performances, and the satisfactory results are obtained for C band satellite communication applications. © 2010 Wiley Periodicals, Inc.
