For a high-density multilayer substrate ALIVH, balanced pair transmission lines on which 60-GHz signals can be transmitted are proposed. First, it is shown that transmission of millimeter wave signals is difficult due to impedance mismatch of the vias in the conventional unbalanced transmission lines. Further, it is shown that transmission at up to 90 GHz is possible by a design such that the microstrip line on the surface, the strip line in the inner layer, and the vias connecting each layer have the same transmission line spacing and the same characteristic impedance.
