Abstract
A flexible coplanar waveguide low profile high speed transmission circuit and a fabrication method of the transmission line structure are provided. The flexible coplanar waveguide low profile high speed transmission circuit includes a first flexible substrate, a second flexible substrate, a circuit layer, a first electromagnetic interference (EMI) shielding film and a second electromagnetic interference shielding film. In the fabrication method, the circuit layer is disposed between the first flexible substrate and the second flexible substrate and laminated. Then, electromagnetic interference shielding films are adhered to the flexible substrates. The flexible coplanar waveguide low profile transmission circuit satisfies following equation: where DT is the distance between a grounded line and a signal transmission circuit, TS is the thickness of the flexible substrate, and DK is the dielectric constant of the flexile substrate.
