<p>PURPOSE: To facilitate positioning for attachment and to prevent the position deviation by fitting a small projection formed on a dielectric strip to a recessed part formed on a parallel conductor plate and positioning the dielectric strip. CONSTITUTION: Two small projections 3a and 3b are formed separately in the longitudinal direction on the lower surface of the dielectric strip 3 to be inserted between upper and lower parallel conductor plates 1 and 2 and the dielectric strip 3 is held there between the upper and lower parallel conductor plates 1 and 2 while the small projections 3a and 3b are fitted to the recessed parts 2a and 2b formed on the lower side parallel conductor plate 2. The shape of the recessed parts 2a and 2b is defined so as to make the joined surface of the dielectric strip 3 be tightly adhered to the parallel conductor plate 2, to make play in a fitted state small and to accurately perform positioning. Also, it is possible to form the small projections on the upper surface of the dielectric strip 3. Also, it is possible to provide the small projections on both upper surface and lower surface and stipulate the position relation of the upper and lower parallel conductor plates 1 and 2.</p> |
