ANTENNA Russian patent published in 2019 - IPC H01Q19/10 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna technology and can be used both in radar and in radio navigation. Antenna contains a metallized dielectric plate placed parallel to the flat reflector, matching device and microstrip line, and its width is selected based on the condition of matching the input resistance of the radiator and the coaxial line. To achieve the technical result of reducing the transverse dimensions of the radiator while maintaining high gain and a wide operating frequency range, emitter is made in the form of an elliptical window in the metallization of the dielectric board, on its inner side facing the flat reflector. Matching device is formed by a U-shaped microstrip loop connected to the microstrip line with a smooth transformer. Ends of the U-shaped microstrip loop are made with a turn of 90°.

EFFECT: reducing the transverse dimensions of the radiator while maintaining high gain and a wide operating frequency range.
