FIELD: antenna technology.
SUBSTANCE: device relates to antenna technology, and in particular to microwave antennas, and can be used in radio receivers and transmitters of radar and communication systems for receiving broadband radio signals and systems where antennas omnidirectional in the azimuth plane are required. The technical result is achieved by the fact that the balanced printed emitter contains a dielectric substrate, excited by the input signal, the first waveguide integrated into the substrate with the main wave of the H10 type, the converter of the H10 wave into the H20 wave with a metallized hole passing through the thickness of the substrate, exciting the Vivaldi emitters, the second waveguide integrated into the substrate with the main wave of the H20 type, the first electrode of the first Vivaldi emitter, having a straight edge coinciding with the edge of the substrate and the edge diverging exponentially and located on the first side of the substrate, combined along the straight edges of the second electrode of the first Vivaldi emitter and the first electrode of the second emitter, located on the second side of the substrate, the second electrode the second Vivaldi emitter, the straight edge of which coincides with the opposite edge of the dielectric substrate and located on the first side of the substrate, metallized holes passing through the dielectric substrate and forming the side walls of the waveguides integrated into the substrate.
EFFECT: balanced slot emitter with a simplified design, with lower reflection losses, with an increased size of the antenna aperture in the horizontal plane, an increased gain, and a narrower width of the directional pattern in the azimuthal plane.
