BROADBAND RED-MICROPASS ANTENNA Russian patent published in 2018 - IPC H01Q13/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, in particular to broadband antennas of the microwave range. Antenna contains a horn and a resonator, which is a special microstrip antenna and powered through the side wall of the speaker using a L-shaped wedge-shaped microstrip balun. Horn is made of metal in the form of a straight cylinder with a rectangular cross-section, rear wall of which is a screen-reflector. Metal plate of the resonator is parallel to the screen-resonator and represents a symmetrical vibrator of a special shape, the longitudinal axis of symmetry of the arms of the symmetrical vibrator of the resonator coinciding with the axis of symmetry of the horn opening and perpendicular to the two opposite side walls of the horn. Center of the symmetrical vibrator coincides with the horn opening center.

EFFECT: technical result consists in reducing the displacement of the antenna phase center in the operating frequency band.
