ANTENNA Russian patent published in 2005 - IPC

FIELD: superbroad-band microwave antennas that can be used in phased antenna arrays for communication systems, superbroad-band radars, and metrology.

SUBSTANCE: proposed antenna incorporating ability of forming linear phase-frequency characteristic has first and second additional metal plates as well as sections of input and additional input transmission line which are connected on one end to second main and second additional metal plates, respectively, and on other end they are interconnected through jumper; first side edges of surfaces of first and second main and second additional metal plates are expanding in direction of longitudinal coordinate of antenna; first side edge of first main metal plate on length between first coordinate surface and second one and first side edges of second main and second additional metal plates on length between first coordinate surface and third one are disposed on third coordinate plane. Alternative design of antenna incorporating newly introduced first metal plate installed symmetrically to first main metal plate relative to coordinate surface parallel to second coordinate plane is given in description of invention.

EFFECT: enhanced gain, reduced level of electric-field cross-polarized component, reverse and side radiation level, and background level.
