- Аннотация: This article is devoted to the study of the possibilities of increasing the spectral efficiency in MIMO systems by using antennas with substrates of biisotropic and bianisotropic chiral metamaterials and various types of fractal emitters. Fractal structures in the form of a Sierpinski triangle, Koch and Gilbert curves, as well as a dipole triangular antenna of complex configuration were used. The method of designing a chiral metamaterial based on helices, which provides the implementation of the specified values of resonant frequencies, is shown. The spectral efficiency was calculated by using one of the variations of the Shannon formula, which includes a complete matrix of Z-parameters calculated using electrodynamic modeling methods based on integral equations. It is shown that the use of such antennas with the fractal geometry of the emitters located on chiral substrates allows to reduce the mutual influence between the emitters, and, in turn, to increase the spectral efficiency in several frequency ranges compared to traditional solutions.
