AIRCRAFT VIBRATOR TYPE ANTENNA Russian patent published in 2019 - IPC H01Q13/10 

FIELD: radio equipment and communications.

SUBSTANCE: invention relates to the field of radio equipment, in particular to the field of aircraft antennas. It can be used in decimeter wavelength range as transmitting or receiving antenna, including the aircraft (AC) antenna, having the path section with lowered atmospheric pressure. Aircraft vibrator type antenna contains open at one end cylindrical resonator with cover, filled with a dielectric, a coaxial connector, a tuning element, an emitter located above the tuning element in the parallel to the resonator base plane. Additionally, an automatic frequency control device is introduced, installed on a board installed in formed by the cylindrical resonator cover and base cavity, containing in series connected directional coupler, detector section, control circuit, reactivity change circuit, which is connected to the tuning element. In the dielectric, a power supply element is additionally installed, which is via directional coupler connected to the coaxial connector, in the dielectric the control element is also installed in the same plane with the power supply element, and diametrically opposite to it. At the resonator open end, a radio transparent heat shielding insert is installed with a radiator fixed inside it in the form of a flat plate with the formation of the radiator capacitive coupling with the power supply and tuning elements, which axes of symmetry are located perpendicular to the cylindrical resonator base, at that, the supply, tuning elements axes of symmetry and the radiator axis of symmetry are located in the same plane of the antenna longitudinal cross-section.

EFFECT: enabling the possibility to take into account of the antenna resonant frequency shift and the antenna alignment in the wide frequency band, increase in the manufacturability.
