Abstract
A printed circuit board utilizes asymmetric striplines to accommodate a large number of transmission lines on a six-layer board. The asymmetric striplines are formed from two signal layers that are sandwiched between two reference planes such that the traces in each signal layer form asymmetric striplines with the two reference planes. Two additional signal layers are arranged on the outside of the reference planes so as to form microstrips with the reference planes.
