CIRCULAR POLARISATION SLIT STRIPLINE LEAKY-WAVE ANTENNA WITH SLIT RADIATOR WIDTH DISCONTINUITY Russian patent published in 2016 - IPC H01Q13/10 

FIELD: radio engineering, communication.

SUBSTANCE: circular polarisation slit stripline leaky-wave antenna with slit radiator width discontinuity includes a dielectric substrate, on the upper metal-coated side of which there are slit radiators wound in a spiral around the geometric centre of the antenna, not connected to each other and including straight and bent segments of different length. The slit radiators have a larger slit width at the antinodes of the high-frequency H field.

EFFECT: improved technical characteristics of the antenna, particularly a low elliptic coefficient and high suppression of cross-polarisation.
