Abstract: A multi-layer circuit structure includes a differential transmission line pair and at least one conductive pattern. The differential transmission line pair includes first and second transmission lines disposed side by side. Each of the first and second transmission lines includes first and second segments connected to each other. An spacing between the two first segments is non-fixed, and an spacing between the two second segments is fixed. A first zone is located between the two first segments, a second zone is opposite to the first zone and located outside the first segment of the first transmission line, and a third zone is opposite to the first zone and located outside the first segment of the second transmission line. The conductive pattern is coplanar with the differential transmission line pair and disposed on at least one of the first, second and third zones. The conductive pattern is electrically connected to a reference potential and electrically insulated from the differential transmission line pair.
