The subject of research is the influence of geometrical parameters of all-metal loudspeakers and loudspeakers from separate conductors on their electrical characteristics. The purpose of the work is to develop methods and techniques of constructive synthesis of a parabolic antenna radiator based on a control from individual conductors for the antenna system of a promising radio relay-tropospheric communication station. Research methods: For creating new mathematical model of an all-metal horn and methods of its calculation, the methods of Hertz's dipole theory, Maxwell's system of equations, the method of inductive electrophysical forces and the calculation for an all-metal horn were used. The main tasks of the work are: - analysis of the construction of modern radio relay and tropospheric communication lines and design features of the state of radio communication; - comparative analysis of design features of irradiators; - analysis of methods for calculating horn antennas; - modeling of the parabolic antenna irradiator on the basis of control from separate conductors; - development of a technique for constructive synthesis of holes from individual conductors. - optimization of radiation patterns of the all-metal horn by changing the angle of opening and the length of the horn from individual conductors. The results obtained in a research work can be used in the educational process of ISZZI KPI Igor Sikorsky at a special department № 3 in the development of methodological materials for laboratory work on the study of the loudspeaker for the discipline "Electrodynamics and Propagation", "Design of antenna devices", "Telecommunication Technologies" and "Fundamentals of Telecommunications" Product Description popup.authors Gordienko Yurii Viktorovich Dubina Vitalii Olekrandrovich Laschenko Vladislav Sergeevich Mavrina Olena Sergiivna Marchenko Andrii Olekrandrovich Sboev Roman Yurievich Sinitsyna Natalia Grigorovna Fedorivskii Pavlo Valentinovich Hranovska Tatyana Vasilevna popup.nrat_date 2021-06-04 Close
