In ground radio line of communication conditions of propagation of electromagnetic waves are diverse and complex, and they affect differently depending on what the length of the emitted electromagnetic wave and the location of the antennas of the receiver and transmitter. As a result, the research and optimization of such lines with the use of mathematical models is of great interest. The possibility of optimization of ground radio line of communication by methods of mathematical modeling is investigated. The article presents the results of the study of the ground radio line of communication line in centimeter and millimeter wave ranges using its generalized mathematical model, taking into account the complex structure of the electromagnetic field at the earth's surface. The possibilities of optimizing the radio line using a systematic approach is evaluated. The optimization criteria providing the best characteristics of the ground radio line of communication are proposed. The mutual spatial position and dimensions of the antennas of the receiver and transmitter found as a result of modeling allows to increase the level and stability of the received signal in the given operating conditions. The obtained results can be used in the design of ground radio line of communication.
