PLANAR LEAKY-WAVE ANTENNA Russian patent published in 2014 - IPC H01Q13/28 H01P3/16 

FIELD: radio engineering, communication.

SUBSTANCE: planar leaky-wave antenna includes a planar dielectric waveguide, an array of parallel metal strips, a coupling element with a transmission feed line, a stripline conductor with rows of lateral stripline protrusions on the left and right side, wherein the planar dielectric waveguide has one dielectric layer, the stripline conductor lies on the outer surface of the dielectric waveguide in the same plane as the strips of the array, the rows of lateral stripline protrusions on the left and right side of the stripline conductor are offset relative each other along the edges of the stripline conductor by a distance equal to half the repetition period of the protrusions, the centre stripline of the array serves as the stripline conductor, and the distances between the longitudinal axis of the centre stripline and the centres of the nearest striplines of the array on the left and right side are equal.

EFFECT: providing symmetry of the shape and side lobes of the beam pattern, simple design.
