STRIPLINE SLIT ANTENNA (VERSIONS) Russian patent published in 2011 - IPC H01Q9/00 

FIELD: physics.

SUBSTANCE: stripline slit antenna has a main and auxiliary stripline slit antenna with a conductor in form of a cylindrical spiral, a bridge device and has two versions. In the first version, the auxiliary striplne slit antenna is a mirror for the main antenna. In the second version, the auxiliary stripline slit anntena is identical to the main antenna and is placed in series after the main antenna. In both versions, inputs of the main and auxiliary antennae are connected to outputs of the bridge device, and the two antennae have a common housing.

EFFECT: double-channel stripline slit antennae widen the scanning sector, increase accuracy of determining angular coordinates of a target, improve amplitude-phase characteristics and parameters of the antenna direction pattern and increase efficiency.
