NON-DIRECTIONAL ANTENNA OF HORIZONTAL POLARIZATION Russian patent published in 2021 - IPC H01Q9/00 

FIELD: antenna technology.

SUBSTANCE: invention relates to antenna technology, in particular to transceiver antennas with a circular radiation pattern (RP) in the azimuthal plane, designed to emit and receive waves of horizontal polarization. The result is achieved by the fact that a non-directional horizontal polarization antenna contains three horizontal half-wave vibrators, each of which is deployed relative to the neighboring one by 120°, and a reflector in the form of a disk with a diameter of half the wavelength located in the lower part of the antenna at a distance of a quarter of the wavelength from the vibrators, while for the formation of a circular azimuthal RP, the vibrators are connected to the outputs of a three-channel power divider providing their in-phase equal-amplitude excitation, the shoulders of the vibrators are made in the form of concentric arcs, a three-channel power divider is implemented on the basis of parallel branching of a common coaxial line into three asymmetric strip lines, each of which is connected to the shoulders of the corresponding vibrator.

EFFECT: reducing the unevenness of the circular azimuthal RP, simplifying the design and reducing the dimensions.
