LOW-PROFILE SIX-LOOP SHORT-CIRCUITED SLIT ANTENNA FOR MICROWAVE FREQUENCY RANGE Russian patent published in 2013 - IPC H01Q1/00 

FIELD: radio engineering, communication.

SUBSTANCE: microwave frequency antenna, having a cosecant-shaped beam pattern in the vertical plane, has a flat metal base. At the centre of the base there is a device socket for a radio-frequency connector, wherein the centre conductor of the back part of the connector is an elementary radiator tuned to the medium frequency of the operating range. The centre conductor is connected to an additional current-conducting flat circular screen lying over the base of the antenna. The screen is connected to the base of the antenna by symmetrically lying six metal short-circuitors.

EFFECT: simplifying design while improving quality of communication.
