Leaky coaxial cable

摘要

A leaky coaxial cable wherein the inner conductor is helically wound with its winding direction reversed alternately at a predetermined interval which is approximately equal to 1/2 of the wave length of the operating frequency and the outer conductor is a conductor tube having a gap or straight array of slots provided along the cable axis. The leaky coaxial cable of the present invention, which is installed horizontally, leaks out a vertically polarized leaky wave which is very suitable for use in radio communication systems.
