Research goal - creation of high accurate mathematical models of following radiators: open ends rectangular or circular waveguides, vibrators (in the presence of screens), slots, vibrator -and-slots, horns, scanning and multi-beam reflector antennas. Research techniques - theory, computer analysis. The mathematical models of the following radiators was worked out: the open end of the rectangular waveguide with infinite flange (on the base of L.Levin's solution) and the open end of the circular waveguide, which is excited with the symmetrical wave modes (on the base of L.A.Vainstein's technique); a slot radiator cut in the rectangular waveguide butt-end and wave-guide slot narrow-band antenna-filter; the "reflector - irradiator" system (with the separate subprograms for calculating the reflector and irradiator parameters); non-phased and two-beam angle and profiled antenna arrays; the vibrator -and-slot radiator in form of Г- shaped vibrator dipped into the slot cut in the infinite screen; the vibrator situated on the finite distance from rectangular screen and corner reflector. The zoned parabolic antenna with less deep than solid one and program for calculating its profile were proposed. Possibilities of descreasing of side lobes and optimization of the main lobes of the sum and difference patterns of the angle and non-phased antenna arrays were investigated. SRW results may be recommended for use in scientific -and - industrial organizations and Institute for Scientific Researches of National Academy of Science of Ukraine for developing and designing antennas of radio - electronic system of different intending.
