In this article the subject of research is an exciter for the microwave distribution system. The microwave distribution system for which the selected method of excitation of electromagnetic waves is a coaxial line has been considered. The microwave exciter includes PTFE plate with the thickness making the impedance of the exciter equal to 50 Ohms, which allows to match it with the coaxial line with the same impedance in a wide frequency range. Based on the obtained data, a model has been made using Ansoft HFSS 11 software. In this program, the built system has been simulated, graphs of VSWR and losses frequency characteristics, magnetic field intensity and radiation patterns of distribution system have been also received. In the selected variant of the exciter of microwave distribution system we succeeded in achieving losses between inputs not worse than -22 dB, VSWR values no worse than 1,2 and the constancy of the radiation pattern width in the working frequency range.
