Abstract
PURPOSE:To improve the directivity of a radio-wave beam by shortening the wavelength in a waveguide-shaped dielectric by forming a metal film around the dielectric by vapor deposition or plating. CONSTITUTION:On the entire surface of dielectric 1 having dielectric constant epsilonr except convex radio-wave radiation opening parts 4 formed at fixed intervals, thin metal film 2 is formed by vapor-deposition or plating and the entire surface of thin film 2 is molded with molding material 3 to a thickness equal to the height of the convexes. In this case, size l in the long size direction is determined satisfying the set expression based upon the relation of wavelength lambda0 of a radio wave to be used and dielectric constant epsilonr. Thus, miniaturization in terms of size and reduction in weight can be attained as well as directivity improvement and further since the thin metal film is hermetically sticking to the dielectric, the generation of an arc entailing an electric power loss can be eliminated without decreasing the dielectric constant equivalently.
