  • Ultra-high-frequency leaky coaxial cable
    Patent number: 3963999
    Abstract: A leaky coaxial cable for use at ultra-high-frequency has, between an outer conductor having slots for the radiation of electromagnetic wave and a protective sheath covering the outer conductor, a dielectric layer with electrically low loss, thereby decreasing the transmission loss. By arranging the slots of the outer conductor in a predetermined relation, it is possible to provide a leaky coaxial cable having a wide band characteristic and less transmission loss.
