Abstract. Currently, there is a need to develop new technical solutions for antenna systems for mobile radio communication systems with improved electrical and mass-dimensional characteristics.

As a result of the analysis of the currently conducted fundamental and applied research, it was found that the use of various composite structures (metamaterials) can improve the characteristics of antennas and antenna-feeder path devices.

At the same time, there is an urgent scientific and technical problem of developing adequate electrodynamic and mathematical models of antennas and antenna-feeder path devices based on metamaterials for the correct calculation of their characteristics.

The purpose of the work is theoretical and experimental studies of the characteristics of a two-element common-mode antenna array with a reflector made of a spiral metamaterial for mobile radio communication systems.

The above research results have shown that the use of such antenna arrays is advisable when both types of polarization (vertical and horizontal) are required. Such an antenna array can increase the efficiency of communication systems, for example, in a wooded area.

The proposed common-mode antenna array with a chiral metamaterial reflector can be used on mobile objects of digital and analog radio communication systems operating, including in the mode of pseudorandom tuning of the operating frequency.
