HF-BAND BROADBAND ANTENNA SYSTEM Russian patent published in 2025 - IPC H01Q21/24 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna engineering and serves as a receiving-transmitting antenna for deployed radio centres. In the antenna system, the linear radiating elements are connected by their lower ends at one point at the base of the mast with the vertical polarization signal connection unit, and in the upper part of the mast there is a unit for connecting a horizontal polarization signal, and additionally from the upper part of the mast symmetrically on both sides relative to the guy with the radiating elements of vertical polarization, two sets of fan-shaped guy wires, connected in the upper part to one point, which is connected to a horizontal polarization signal source, forming linear radiating elements of horizontal polarization with full length of not more than 0.5 of the wavelength of the operating range, which are located in the sector of angles of 45-90 degrees, counting from the plane of arrangement of linear radiating elements of vertical polarization.

EFFECT: obtaining two linear polarisations with a high level of isolation between polarisations at the same height of the mast and the area of arrangement of the antenna system, which enables to implement two independent communication channels in the system.
