LEAKY COAXIAL ANTENNA Russian patent published in 2010 - IPC H01Q13/20 

FIELD: physics; radio.

SUBSTANCE: invention relates to a radiating coaxial antenna (10) comprising an inner conductor (1), a dielectric (2) around the inner conductor (1), and a first shield conductor (4) placed around the dielectric (2), the first shield conductor having openings (41) distributed in the longitudinal direction of the inner conductor (1) and being adapted such that electromagnetic energy passes through the openings (41). A second shield conductor (5) placed around or under the first shield conductor (4), the second shield conductor (5) being adapted to cover at least a number of the openings (41) of the first shield conductor in a shielded section (S1-S12). The second shield conductor (5) is arranged discontinuously in the longitudinal direction of the antenna (10) defining uncovered parts (AS1-AS12) of the first shield conductor (4) in the longitudinal direction of the antenna, which are adapted such that electromagnetic energy passes through the uncovered parts (AS1-AS12).

EFFECT: present invention proposes double-layer shielding to improve properties of a radiating coaxial antenna with respect to aviation applications for example.
