The propagation factor of the Niobium-based distributed Superconductor-Insulator-Superconductor (SIS) tunnel junction has been modelled for frequencies between 70-200 GHz. In the modelling, the distributed SIS junction was simulated as a microstrip distributed component. Furthermore, in our studies, the reactive part of the SIS tunnel junction quantum admittance was included in the model circuit diagram. It was shown that the SIS quantum reactance has significant effects on both the loss factor, Re (γ), and phase factor, Im (γ), where γ is the complex propagation constant.
