Low loss dielectric waveguide joint and method of forming same

摘要

The air gap in the joints between millimeter wavelength, dielectric waveguide circuit components is filled with a slurry made from an inorganic dielectric, such as barium titanate; and an organic binder, such as cellulose nitrate. The proportions of the dielectric and binder are taken so as to have a composite dielectric constant the same as that of the components being joined. This removes breaks or discontinuities and in turn reduces the insertion loss at the joints.
