SLOTTED WAVEGUIDE ANTENNA ARRAY Russian patent published in 2016 - IPC H01Q13/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, particularly, to waveguide-slot antennas. Slotted waveguide antenna array consists of forming grid lines. Each line ends with lateral waveguide-coaxial junction, which excites a half-wave transverse slot in narrow wall of line, for this purpose on rod of waveguide-coaxial junction before slot there is pin. At that, waveguide is made rectangular. Rectangular transverse slot is made at end of waveguide. During operation waveguide divides fed power on branched passing and reflected, and phase of terminal wave emitted by radiator is determined by length of path of waveguide wave from penultimate slot to radiator with due allowance for wave length in waveguide-coaxial junction.

EFFECT: technical result is increased efficiency, and antenna gain.
