Patent abstract
An leaky coaxial cable antenna with high radiation efficiency and low insertion loss is described. The outer shield of the coaxial cable is constructed to facilitate energy transfer between the bifilar mode and the monofilar mode by constructing the outer conductor of a first conductive strip wrapped in a spiral about the dielectric and a plurality of second conductive strips wrapped in a counter spiral about the first but spaced serially along the length of the coaxial cable such that portions of the cable are wrapped by a single spiral and the other portions are wrapped by two spirals.
