Research and development of antenna complexes for MIMO with polarization division

An increasing increase in the amount of transmitted information in wireless radio networks makes it necessary to search for and develop technologies that can improve spectral efficiency. One of these technologies is MIMO. MIMO technology is successfully used in cellular communication systems and Wi-Fi networks. An urgent task is also to increase the spectral efficiency in special-purpose networks. Based on the conducted research, the procedure for designing antenna complexes in MIMO systems was developed. An experimental study of the components of antenna complexes with polarizing diversity was performed. In particular, an antenna complex consisting of two orthogonal log-periodic antennas combined on one traverse was developed. It is shown that the measured characteristics are in good qualitative and quantitative agreement with the characteristics obtained using the developed electrodynamic model of the antenna complex with polarization diversity.
