At present, an important scientific and technical task is development of solutions of antenna systems for receiving short-wave (HF) radio centers. The main approach to upgrading receiving HF radio centers is associated with replacement of existing directional antennas by multibeam active ring antenna arrays.

In order to improve the energy characteristics of HF radio communication networks, an approach is promising, the essence of which is to receive several types of polarization components of electromagnetic waves and their combinations, followed by a weighted summation. A promising option in this case is the use of three-orthogonal antenna elements, which are three mutually orthogonal vibrators with low-noise amplifiers based on high-impedance differential amplifiers. The article presents the achieved electrodynamic characteristics of such solutions.

These tri-orthogonal antenna elements are able to isolate various types of wave polarization using the developed polarization processing unit. This allows improving the quality of communication. The use of three-orthogonal antenna elements with polarization processing units as a part of a ring antenna array opens up broad possibilities for upgrading HF radio centers.
