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

摘要

This paper presents a comparative study of the losses of 4 commonly used planar transmission linesrn(microstrip, coplanar, grounded coplanar and stripline). The losses are separated into conductor dielectric andrnradiation losses and investigated on 3 different technologies. These technologies are thin-film polymer substrate, lowrncost printed circuit board and glass. The attenuation on these 4 lines is computed using quasi-static methods and fullrnwave simulations. The goal is to get an insight on the different frequency-dependent behaviour of the lines to providernthe optimal line configuration for a given substrate technology and frequency region.
