Claim:
1. An apparatus comprising: a first component including a first ground line, a second ground line, and a first transmission line in parallel oriented in a first direction, wherein the first transmission line is disposed between the first and second ground lines, wherein the first ground line has a first line segment and a second line segment connected together, wherein the first line segment is oriented in the first direction and the second line segment is oriented in a second direction being orthogonal to the first direction, and a second component including a second transmission line, a third ground line, and a fourth ground line in parallel oriented in the first direction, coupled with the first component, wherein the first transmission line and the second transmission line are each comprised of: a substrate; a p-well or n-well within the substrate; a shielding layer over the p-well or n-well; a plurality of intermediate conducting layers over the shielding layer, the plurality of intermediate conducting layers vertically aligned with the p-well or n-well and coupled by a plurality of vias; and a top conducting layer over the plurality of intermediate conducting layers, wherein the second transmission line includes an elongated slot that is oriented in the first direction and extends through the shielding layer, the plurality of intermediate conducting layers, and the top conducting layer, wherein the shielding layer is a metal layer and directly contacts the P-well or N-well within the substrate.
