ABSTRACT:
A nonradiative dielectric line is provided which solves problems concerning the relative positioning of the parts, mass production, and variations in electrical characteristics of a dielectric strip, and which makes integral molding using injection molding technology possible. A height of a dielectric in the propagation area is made higher than the height in the non-propagation area, and a dielectric layer having a low dielectric constant is provided in the non-propagation area. Thus, the thickness of the dielectric layer in the non-propagation area can be increased.
