An antenna assembly having patterned conductive films on the surfaces of a dielectric hexahedron with compatibility to mass-production, wherein the conductive films are formed on protuberances formed on the surface of the dielectric hexahedron on which protuberances and depressions are formed. In one embodiment, the dielectric hexahedron includes convex portions serving as the protuberances and concave portions serving as the depressions. A conductive film may be formed on the protuberances by roll coating, sputtering, evaporative deposition, and electroless deposition, thereby producing inexpensively a high quality antenna assembly having a circuit pattern formed thereon.
