Abstract
A leaky-wave antenna whose radiation pattern is uniform in circumference is made of double-sheath helices. The fundamental characteristics of this antenna are discussed theoretically and experimentally. A method which produces a tapered field along its aperture to effect reduced sidelobe level, and the relationship between the dielectric supporter for the sheath helices and the wavenumber are also discussed.
