STRIPPED SLOT ANTENNA Russian patent published in 2011 - IPC H01Q13/00 

FIELD: radio engineering.

SUBSTANCE: stripped slot antenna includes screening housing with cavity, isolator in a form of dielectric pin with outer spiral groove located inside screening housing, conductor in a form of cylindrical spiral located at isolator. Slowing structure of spiral form is very advantageous for antennae with large scanning sector (γ=±90°) at comparatively small working frequency range (less than 2%). Besides, non-symmetrical stripped transmission line with spiral conductor provides a better compliance because it is homogeneous. The quantity of radiating elements in the structure of stripped slot antenna is defined by spiral pitch and can be significant.

EFFECT: increase of scanning sector, improvement of amplitude-phase characteristics, elimination of sudden resonance, improvement of antenna directivity diagram parametres and efficiency increase.
