ULTRA-BROADBAND COMPACT HIGH-DIRECTIVITY HORN-STRIPLINE ANTENNA Russian patent published in 2006 - IPC H01Q13/02 

FIELD: antenna engineering.

SUBSTANCE: proposed antenna has disk resonator in the form of flat round plate coaxially and symmetrically mounted on protruding part in center of internal surface of reflecting screen made in the form of flat wall on narrow end of truncated conical horn; disk resonator plane is parallel to reflecting screen. Coaxial feeder line is brought in through reflecting screen and its central conductor is connected to disk resonator edge by means of lug made in the form of truncated cone whose symmetry axis is perpendicular to disk resonator plane. Lug dimensions are stipulated. Outer surface of reflecting screen can be coated with radio-absorbing material.

EFFECT: minimized height and side-lobe level at maximal gain of antenna.
