Karazin popup.description2 The object of study is a small-sized high-performance, broadband, multiband antennas and antenna arrays, radioceramics antennas. The purpose of the work is the development of principles of designing, manufacturing techniques and calculation methods of antennas and antenna arrays with electrodynamic mass-dimensional characteristics. The main results and its novelty consist of: - The electrical conduction currents flow processes in a small antenna and their influence on the formation of bias currents, to ensure effective emission of electromagnetic energy is investigated. Clarified multiparameter dependence of dynamic characteristics of electromagnetic fields from the geometric dimensions of antennas and their construction. Established methods of design and manufacturing technology of small-sized, high-performance, wideband and multi-band antennas and antenna arrays for communications in the range from 1 to 3000 MHz; - developed a method for the design of antennas, based on radio ceramics for conducting radio communications in difficult conditions (high dust, ionized medium, dense vegetation); - designed wideband array antenna for the frequency range 100-300 MHz 600x600x100 mm dimensions and a gain in the range of 8-10 dB; - designed and manufactured dual-band antenna array of the axial radiation frequency bands 150-250 MHz and 450 - 1000 MHz with dimensions 400x400x70 mm and a gain in the range of 7-9 dB; - designed and made small-sized antenna to all cellular bands operating frequency range 800-2500 MHz with dimensions 80x30x10 mm and gain within 8 dB. The manufactured experimental devices have technical and economic characteristics which exceed foreign ones and its does not have analogues on this time. Recommendations for the use of the results. The results can be used in the development of compact, wideband antennas and antenna arrays axial and lateral radiation. Also, the development of small dielectric antenna with significantly weakened reactive area of radiation, which significantly increases the level of environmental safety.
