We have experimentally defined the propagation constants of several kinds of transmission lines on multilayer printed circuit boards using an improved error removal scheme and via hole structures that minimize coupling. We have also clarified the frequency dependency of the loss and the velocity of the signal propagation in the structures. The accuracy of the determined values was con-firmed at a maximum frequency of 14 GHz by comparing them with the theoretical values derived from the TEM approximation.
