High frequency multilayer circuit structure and method for the manufacture thereof |
摘要 |
In a Conductor-Backed Coplanar Waveguide (CBCPW) structure, an effective dielectric constant of a parallel plate waveguide is higher than that of a Coplanar Waveguide (CPW), so that a parallel plate leakage is generated. To reduce the parallel plate leakage, the present invention provides air cavities, whose dielectric constant is low, in a multilayer circuit so that the effective dielectric constant of the parallel plate waveguide of the CBCPW structure can be lowered.
