Special types of coplanar transmission lines suitable up to MM-wave bands

Abstract

This paper contains an investigation of two special types of coplanar transmission lines: an asymmetric micro-coplanar line and a new configuration of coplanar line with additional semi-infinite upper ground planes. The conformal mapping method is used to obtain closed-form expressions for basic parameters of both lines. The dispersion and attenuation characteristics are investigated using semi-empirical analysis up to THz frequency bands.
