Karazin popup.description2 Object of study - high-efficiency, wide bands and multi bands small sizes antennas and antennas on the basis of materials from radioceramics. Purpose - development of principles of constructing, technologies of making and methodology of calculation of antennas with the electrodynamic parameters and the parameters of sizes and mass descriptions set in advance. Method of research - theoretical and experimental research of electric processes of flowing of currents of conductivity in small sizes antennas and their influence on forming of currents of mixing, providing the effective radiation of electromagnetic energy. The main results and their novelty. Basic results and scientific novelty of project consist: - in the receipt of new technologies of planning and making of small, high-efficiency, wide bands and multi bands antennas and antennas with the diminished level of radiation in a near zone. It antennas in basis of work of that are stopped up principle of association in one antenna electric and magnetic emitters, and antennas on the basis of radioceramic materials that practically does not have a reactive zone of radiation outside an own construction; in the improvement of technology of planning of the known aerials and in development of new technologies of antenna design of the different setting; - in development of methodologies of calculation and planning of antennas on the basis of radioceramics, suitable for the conduct of radio contact in difficult terms(high dustiness, ionized environments, dense vegetation); in development physical and mathematical models of antennas of new types, algorithms and software for the calculation of their electric descriptions and constructions; in making of experimental standards of wide bands and multi bands small sizes antennas of new type for the wireless stations with the wide range of frequencies(200-2000МГц), antennas for mobile telephones, handie-talkies and devices for diagnosticating of the state of health of man; -- in making of experimental devices of small sizes antennas for modern navigationals(GPS, GLONASS) with the enhanceable level of strengthening and improved diagram of orientation. Making experimental devices on the descriptions and technical and economic results indexes exceed foreign developments and does not have analogues on this time. Testing results: based on fundamental research published 11 research articles in scientific journals and made 24 presentations at international conferences. Received 2 patents of the foreign states and on5 patents of Ukraine, filed 7 patent applications. Recommendations for the use of the results. The got results and recommendations can be drawn on at development of new types of antennas of different frequency range and antennas with the considerably weak reactive zone of radiation. That promotes their ecological strength security substantially. As a result of implementation of this R & D laboratory work is put "Registration of parameters of hemodynamics". Ceramic antenna also found application as a medical sensor of pulse wave. By means of the worked out antennas that is used as touch-controls, it was succeeded to get data about the complex inductivity of biological objects. KEYWORDS: high-efficiency, wide bands, multi bands, small sizes, antennas on the basis of materials from radioceramics. Product Description popup.authors Євлахов Р. Антоненко Є. Бердник С. Босой В.
