In this paper, the analysis on the dual mode conical horn antennas is made to realize the optimum horn as the primary feed of the offset parabolic antenna for the domestic broadcasting satellite. Such analysis can give rise to the approximate equations and graphs on the beam width, which makes it possible to design the desired conical horn. It has been shown that the radiation charateristics of designed horn antenna built with the dielectric band inside the horn. The designed dual mode horn antenna may provide the useful basis to practical usage of the antenna in the domestic satellite broadcasting communication systems.
