The parameters of the antenna system have a significant impact on the technical appearance and limiting characteristics of radio equipment of various types and purposes. The currently widespread approach to the development of antenna systems, largely based on the use of classical types of antenna elements, in some cases limits the characteristics of radio equipment implemented in practice due to insufficient consideration of the results of the advanced development of radio electronics and the existing groundwork for expanding the capabilities of radio electronic components of equipment. Therefore, already at the present time and in the near future, an innovative scientific and technical reserve should be formed, based on scientifically based principles for creating new generation antenna elements and systems that meet the growing needs of radio engineering.

The paper analyzes the main directions and examples of improving the characteristics of promising antenna systems. Various particular examples demonstrate approaches to optimizing the structure and characteristics of various antennas, which are based on the idea of an antenna element as a complex distributed electrodynamic system. The given examples of improving the characteristics of advanced antenna systems illustrate some of the modern possibilities for effectively optimizing the characteristics of antenna elements, both single and as part of an antenna system.

As a result of a possible generalization of the presented results of antenna optimization and the approaches underlying such optimization, the following directions for improving the characteristics of promising antenna systems can be distinguished: the use of tools of modern automatic design systems for multi-parameter optimization and electrodynamic analysis of the characteristics of an antenna system; representation of the antenna element as a complex electrodynamic system with a large number of degrees of freedom and the subsequent implementation of methods for optimal interaction between the elements of the system according to the criterion of simultaneous provision of a wide range of requirements; application for the synthesis of the structure of antenna elements of the methods of differential geometry and topology, as well as the interdisciplinary methods of the theory of fractals, general systems theory, synergetics, etc.
