Effect of material properties on broadband electrical behavior of coplanar waveguides

We investigate the importance of broadband substrate permittivity and loss tangent data for accurately calculating the frequency-dependent characteristic impedance and propagation constant of ungrounded coplanar waveguides (CPWs). To determine the electrical properties of a CPW, we use a quasi-TEM m...

Zusammenfassung:We investigate the importance of broadband substrate permittivity and loss tangent data for accurately calculating the frequency-dependent characteristic impedance and propagation constant of ungrounded coplanar waveguides (CPWs). To determine the electrical properties of a CPW, we use a quasi-TEM model that takes into account the effects of non-ideal conductors, substrate loss and finite metallization thickness. The propagation of uncertainties is studied with the aid of Monte Carlo (MC) simulations.
