Popis:	In this paper, the simulation of the four-beam antenna system of the centimeter range based on a mirror antenna, whereas the central frequency of the working range was considered 10 GHz. Besides, the comparative analysis was conducted for various antenna systems. Also, the terraced arrangement of four irradiators (feedhorns) was used in a reflector antenna because it showed an improvement in the energy characteristics compared to a flat design. The simulation of a two-mirror antenna presented decreasing in the directional coefficient and increasing in the level of side lobes as result of multipath using case.
