LOW-PROFILE ANTENNA Russian patent published in 2012 - IPC H01Q9/04 

FIELD: physics.

SUBSTANCE: low-profile antenna, having a meandering arched symmetrical strip conductor lying in a plane parallel to an earthed shield, has a central strip, one end of which is connected to the middle of the strip conductor and the second end is connected by a jumper to the shield. The antenna feed point lies on the line of longitudinal symmetry of the central strip at a certain distance from the closed end with the shield. The width of the meandering arched strip conductor increases while moving away from the plane of symmetry of the antenna and towards the open ends. The region of space between the strip conductor and the shield is filled with dielectric material with permittivity greater than one.

EFFECT: enabling transmission or reception, perpendicularly polarised to a flat interface of a dielectric and magnetic field conductor with a circular beam pattern of the antenna in that plane if the antenna lies on the media interface with minimum height of the antenna relative said plane, which is hundredths of the wavelength.
