Abstract :
A quasi-TEM (transverse electromagnetic) analysis for straight and weakly curved planar multiconductor transmission lines is presented. This transverse field of a weakly curved planar multiconductor system is described by the static electric and magnetic solutions of the corresponding axially symmetrical structure. The capacitance and inductance matrices of this system of concentric microstrip rings are calculated using the method of lines. A two-port network consisting of circularly curved transmission lines is calculated and the results are compared with measured values. It is concluded that the proposed method of approximation is suited for analysis of microwave components as well as for high-speed digital circuits with interconnections consisting of curved striplines instead of straight lines with discontinuities
