Innovative HF extraction procedure of the characteristic impedance for embedded planar transmission line on high conductive Si substrate

This paper proposes an innovative and convenient de-embedding method. It is based on the properties modification of a material which is integrated in the architecture of a two ports planar circuit. The main advantage of this technique is that it does not need other complementary circuits to extract the ABCD matrix of the half of the two ports circuit. It also presents a good accuracy as this method is applied to extract the characteristic impedance and the propagation constant of a coplanar transmission line.
