Özet

The radiation from circular cylindrical reflector antennas is treated in an accurate manner for both polarizations. The problem is first formulated in terms of the dual series equations and then is regularized by the Riemann-Hilbert problem technique, The resulting matrix equation is solved numerically with a guaranteed accuracy, and remarkably little CPU time is needed, The feed directivity is included in the analysis by the complex source point method, Various characteristic patterns are obtained for the front and offset fed reflector antenna geometries with this analysis, and some comparisons are made with the high frequency techniques, The directivity and radiated power properties are also studied.
