The article describes the procedure for optimizing the surface profile of the sub-reflector antenna with a two-mirror axisymmetric fit the profile of the reflector antenna made to minimize the impact of a manufacturing error and improve the reflector antenna characteristics. Was conducted as a simulation of antenna parameters and prototype of the sub-reflector and measured characteristics of the antenna with a modified sub-reflectors for experimental verification of the simulation results.
