Numerical simulation of Single-dish antenna radiation characteristics

Abstract

The numerical simulation results of scattering characteristics of a single-dish antenna obtained by commercial Program FEKO and in the specialized program are given. The results are compared on different criteria. The Conclusion is that in almost identical results FEKO program requires much more computing resources. If the feeder is complex, such as monopulse antenna, has simulation using program FEKO becomes impossible.
