ULTRA-WIDEBAND ANTENNA WITH ADAPTIVE BEAM PATTERN CORRECTION DEVICE Russian patent published in 2019 - IPC H01Q3/06 

FIELD: antenna equipment.

SUBSTANCE: antenna has a dielectric substrate, a metal layer located on a dielectric substrate, a slot made in a metal layer with expanding walls along its longitudinal direction and forming an antenna opening, an adaptive correction of the beam pattern, installed in the antenna opening. At that, device of adaptive correction of directional pattern is made of radar absorbent material and is located on opposite side of dielectric substrate, between divergent walls of slot or in dielectric housing, in which it is possible to place antenna, and, thus, is free from contact with walls of slot for selective correction of main lobe of antenna pattern of antenna in aperture.

EFFECT: technical result consists in the possibility of selective adaptation of the main lobe antenna pattern, minimizing power loss when using antenna for radio frequency coverage of target areas.
