Abstract
A film carrier signal transmission line includes a dielectric material having a first, front surface and a second, rear surface opposite the first surface, signal lines buried in the dielectric material for transmitting a super high frequency signal, spaced from the first and second surfaces, and spaced side-by-side at a regular interval; a first grounding film disposed on the second surface of the dielectric material; separating grooves in the dielectric material between adjacent pairs of signal lines, parallel to the signal lines; and second grounding films disposed on the first surface of the dielectric material and in the separating grooves and electrically connected with said first grounding film in the separating grooves. Adjacent signal lines are electrically shielded and crosstalk between signal lines is reduced.
