In this paper, investigations were made of the possibilities of increasing the throughput in MIMO systems by using sub-tables of me-tamaterial in antenna systems. It is shown that the use of such substrates allows to reduce the mutual influence between the emitters. Several variants of antenna systems are considered, the substrate of one of which is made of metamaterial on the basis of right-screw spiral elements metallized from the lower side, and the substrate of the other is made of a dielectric also metallized on one side. On these substrates, there were three symmetrical half-wave vibrator emitters. Such a number of radiators was chosen on the basis that the MIMO 3×3 system is optimal. An estimation of the gain in the system throughput using metamaterials was performed in comparison with traditional solutions. Based on the calculated estimates, it was concluded that the use of such antenna systems in radio communication networks with MIMO is promising.
