A Comparative Study of Microstrip, Stripline and Coplanar Lines on Different Substrate Technologies for High-Performance Applications

This paper presents a comparative study of the losses of 4 commonly used planar transmission lines (microstrip, coplanar, grounded coplanar and stripline). The losses are separated into conductor dielectric and radiation losses and investigated on 3 different technologies. These technologies are thin-film polymer substrate, low cost printed circuit board and glass. The attenuation on these 4 lines is computed using quasi-static methods and full

wave simulations. The goal is to get an insight on the different frequency-dependent behaviour of the lines to provide the optimal line configuration for a given substrate technology and frequency region.
