The goal investigation is developing the mathematical models of the waveguide, horn, reflector and waveguide-slot antennas. Developing the algorithms and computer programs for analysis of the electromagnetic fields and wave processes on depending of the radiating elements exciting manner, their location relatively ones, screens and shape of the latest. Investigations techniques are the theoretical and computer analysis, experiments. The expressions for analyzing the field of the Hertz dipole which is located in an absorbing medium was obtained. The effect of decreasing the resonant vibrator near zone extent for the vibrator of one and half of the wavelength was proved. The strict analytical solution of the problem of radiation of the vibrator -sphere surface system was obtained. The new types of reflector antenna and low-profile vibrator radiators were proposed. The results of this research work can be recomendated for use in Research Institutes and Organizations NASU, NSAU, Ministry of Education and Science of Ukraine, Ministry of Health of Ukraine for elaborating the modern radioelectronic systems of monitoring the environment, communication, TV, medicine devices and for solving the problem of increasing the antenna quality and decreasing the influence of the near zone fields of power radars on the environment and radiophones on the man brain.
