Method for fabricating suspended transmission line

摘要

A method for fabricating a suspended transmission line includes supporting a first conductive trace on a first side of a dielectric support layer. A second conductive trace is supported on a second side of the support layer. The first and second conductive traces are connected at spaced intervals. A first spacer is formed outwardly of the first side of the support layer A second spacer is formed outwardly of the second side of the support layer. A first plate is disposed outwardly of the first spacer and includes a first ground plane displaced from the first conductive trace. A second plate is disposed outwardly of the second spacer and includes a second ground plane displaced from the second conductive trace.
