Measurement and evaluation of Scattering parameters for Surface wave communication-based waveguide at millimetre range frequency band

The surface wave communication-based waveguide (SWW) can replace copper traces to cater millimeter wave frequency bands with loss losses [1], the efficiency of the proposed waveguide has been analyzed considering various factors like surface impedance, dispersion, power flow and attenuation. We have been focused on scattering parameters and Voltage standing wave ratio (VSWR) in this article which are also the fundamental factors to analyze the signal loss, at the frequency range 50 GHz to 150 GHz, we have compared the theoretical entities of these parameters with the simulated results. The entire analysis and comparison prove that the optimum scattering parameters and VSWR were achieved with the proposed SWW as per the expectations than existing copper traces, we have considered copper as the conductor, Teflon as the dielectric material keeping the thickness of the conductor and dielectric at 0.2mm, the entire simulation performed using CST Studio suite.
