Abstract
The dominant loss mechanism is the conductor loss in planar MIC waveguides on low-loss substiates. Superconductors can dramatically reduce the conductor loss, so further reductions in the total loss must come in the dielectric or radiation loss. This paper investigates the use of ~90 K superconductors to reduce the conductor loss. A rigorous mode-matching procedure is used to analyze two microstrip-like transmission lines for their dielectric loss. Total loss reductions are on the order of 10 to 100 times at 10 GHz when using superconductors and dielectric loss reduction techniques. Reductions at other frequencies below 100 GHz should be similar.
