The subject of research is the development of a mathematical model for calculating the directional characteristics of the speaker from low-lying emitters for radio communications and methods of constructive synthesis of the antenna system of radio communications built on low-lying emitters, technical implementation of transmitting and receiving speakers. The purpose of the work is to develop a method of constructive synthesis of the antenna system of radio communication equipment built on low-lying emitters to improve the technical characteristics of mobile radio communication equipment. Research methods - synthesis of antenna systems with the necessary pattern is based on the Hertz vector method, the method of induced electromotive forces, the method of mirror images and analysis of the results. The influence of the shape and number of elements of the antenna system on the formation of its radiation pattern is determined and the calculation for the selection of the optimal design with the required electrical characteristics is established. Based on the results of the research, a mathematical model for calculating the directional characteristics of the AU, built on low-lying emitters for radio communication equipment and methods of constructive synthesis of AU radio communication equipment built on low-lying emitters (technique), which is possible in the absence of time , to build a cost-effective speaker with a realized gain of up to 16 dB.
