CONE-SHAPED REFLECTOR FOR LINEAR FEED Russian patent published in 2011 - IPC H01Q15/14 

FIELD: radio engineering.

SUBSTANCE: reflector includes cone-shaped mirror that has apex angle equal to 90° and has many sections. Inner surface of apex section is made in the form of hollow cone, and inner surfaces of the rest sections are made in the form of conical elements - hollow and flattened, with generatrixes of cones 45° of their walls relative to longitudinal axis. Each next section in the direction from apex of cone-shaped reflector has bigger surface areas of bases of conical elements relative to previous sections. Wall at the bottom of each conical element of the next section is connected by means of connection strap to the wall at the bottom of conical element of the previous section. Connection strap is made in the form of ring and located at an angle of 90° to generatrixes of conical elements of the previous and further section.

EFFECT: increasing amplification coefficient without increasing the length of linear feed.
