ULTRA-WIDEBAND PLANAR EMITTER Russian patent published in 2020 - IPC H01Q21/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna engineering, particularly to ultra-wideband planar antennas. Inner conductor of coaxial line is connected by means of micro strip line with metallisation, made in form of closed frame located on upper layer of printed circuit board, and the outer shield of the coaxial line is connected to the metal coating located on the lower layer of the printed circuit board and repeating the shape of the inner contour of the upper metal coating layer, wherein between the upper and lower layers of metallization of the printed-circuit board a gap is formed, which is controlled by the thickness of the printed-circuit board and the distance between the inner ends of the upper metallisation layer and the lower metallisation layer, and the reflector located at a distance close to a quarter of the wavelength of the middle of the range from the printed-circuit board forms a space filled with a dielectric material or an air layer.

EFFECT: technical result is increased width of transmission of planar emitter to double overlapping of working frequencies.
