Abstract :
This paper discusses the effects that imperfect conductors have on the propagation characteristics of planar transmission-line structures. We present closed-form expressions for the attenuation constant and the resistance per unit length for various planar structures are presented. We also present expressions for predicting the change in the characteristic impedance due to penetration of fields into finite conductors.
