BROADBAND ANTENNA Russian patent published in 2012 - IPC H01Q9/00 

FIELD: radio engineering.

SUBSTANCE: antenna comprises the first dielectric substrate (DS) 1, on one surface of which there is a section of a signal strip conductor (SSC) 2, and on its other surface there is an earth metal plate 3. The second DS 4 is installed perpendicularly to the first DS 1 and is arranged with its side on the section of the SSC 2 in parallel to its longitudinal axis. On one surface of the second DS 4 there is a signal aperture metal plate (AMP) 5, and on the other one - an additional signal AMP 8, which with their side edges are arranged on the section of the SSC 2 and are galvanically connected to it, and along inner side edges are arranged with variable shape. A metal emitting plate 10 is installed perpendicularly and symmetrically to the plane of the second DS 4 along inner side edges of the signal and additional signal AMP.

EFFECT: invention achieves low level of a cross polarisation component of electric field, high coefficient of amplification, with expanded working range into the area of low frequencies without increasing aperture dimensions.
