BROADBAND ANTENNA Russian patent published in 2018 - IPC H01Q9/18 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna equipment. Two analogous antennas with counterweights and broadband decoupling devices and triplexer are introduced into the device. Moreover, two analogous antennas with counterweights and broadband decoupling devices are collinear with the first one and have the dimensions, which correspond to the wavelengths of the neighboring ranges. Lower and upper antennas are hollow. Corresponding inputs of the triplexer are connected to the outputs of the respective antennas, coaxial cables are passed inside the lower and upper hollow rods of each antenna. Counterweights have at least 12 radial wires of the length, which is equal to the total height of the corresponding partial antenna. Angle of the arrangement of the counterbalances relative to the axis of the antennas is 90°. Broadband decoupling devices are formed by means of alternation of inductances, which are connected in tandem to each other with the corresponding coaxial cables. And the inductances are made by means of winding the corresponding coaxial cable onto the dielectric frames or by means of threading the high-frequency magnetic rings, for example the ferrite ones, onto the sections of the corresponding coaxial cable, which are located between the hollow rods of adjacent antennas.

EFFECT: technical result consists in expanding the working bank.
