Dispersion Characteristics of Coplanar Waveguides at Subterahertz Frequencies

Abstract

We present experimental and simulated studies of the dispersion characteristics of coplanar waveguides (CPWs) at subterahertz frequencies. Two types of CPWs were studied, those with wide ground planes and those with narrow ground planes. In both cases, simulations closely followed the experimental results, thus giving us a basis for implementing the simulations in circuit-design modes for a wide range of such waveguides.
