Abstract
The present invention provides a transmission line structure comprising: a dielectric substrate having first and second surfaces; a signal conductive layer selectively provided on the first surface of the dialectic substrate for signal transmission; at least a first non-signal conductive layer being selectively provided on the first surface of the dialectic substrate, and the at least first non-signal conductive layer being separated from the signal conductive layer; and a second non-signal conductive layer being provided on the second surface of the dialectic substrate, wherein the dielectric substrate has at least a conductive region extending in contact with only one of the at least first non-signal conductive layer and the second non-signal conductive layer so that the at least conductive region is separated by the dielectric substrate from remaining one of the first non-signal conductive layers and the second non-signal conductive layer in view of a vertical direction to the first and second surfaces of the dielectric substrate.
