ANNULAR SLIT ANTENNA Russian patent published in 2018 - IPC H01Q11/10 

FIELD: antenna equipment.

SUBSTANCE: invention relates to the meter and decimeter wavelengths antenna equipment and can be used to provide radio communication in these wavelength ranges in stationary and mobile, including flight and lifting, objects of various purposes. Antenna comprises small endovibrator having parabolic portion at its end transferring to the orthogonally disposed in the horizontal plane second small metal annular ring. At that, reduced first annular radiating gap is formed, located between the first large annular ring minimum circumference and the second small annular ring maximum circumference, and the second expanded annular radiating slot, located between the second small annular ring minimum circumference and the disc perimeter circumference.

EFFECT: technical result consists in increase in the elevation angle value to the decimeter range antenna maximum radiation power horizon for provision of the radio communication with communication objects by at least two times.
