Abstract:
1. A ground-plane slotted type signal transmission circuit board for use as a circuit element for integration to a circuit system, comprising: a substrate, which has a first surface and an opposite second surface, and whose second surface is formed with a ground plane; a signal line layout structure, which is laid over the first surface of the substrate for use as a signal conveying channel; a grounding line layout structure, which is laid over the first surface of the substrate and extends alongside the signal line layout structure; a via structure, which penetrates through the substrate for connecting the grounding line layout structure on the first surface of the substrate to the ground plane on the second surface of the substrate; and a slotted structure, which is a cutaway portion of the ground plane on the second surface of the substrate, and which is aligned substantially in parallel to the signal line layout structure on the first surface of the substrate.
