Abstract
A coplanar waveguide, which has parallel conductor strips that are arranged on a substrate and have an electrically insulating intermediate space between one another, wherein a material with a high dielectric constant is arranged on the conductor strips, on their side facing away from the substrate. In this way, it is possible to achieve a line section with a relatively small characteristic impedance.
Claims7
Coplanar waveguide, which has parallel conductor strips that are arranged on a substrate and have an electrically insulating intermediate space between one another, wherein a material with a high dielectric constant is arranged on the conductor strips, on their side facing away from the substrate.
Waveguide according to one of the preceding claims, wherein the length over which the material with a high dielectric constant is applied, or the length of the material with a high dielectric constant, is shorter than the stripline.
Waveguide according to one of the preceding claims, wherein the material with a high dielectric constant has a relative permittivity of at least.
