Abstract

We have investigated both conventional and meandering coplanar microwave transmission lines patterned in Y-Ba-Cu-O/Au bilayers on yttria-stablized zirconia and sapphire substrates. Within the meandering waveguides, the gentre conductor was deformed from a straight line to a meander. Such a layout could be useful for metrological high-T_c superconductor arrays, which are based on series arrays of shunted YBCO bicrystral junctions. The microwave properties of the lines were measured in the range 0-40 GHz at 76 K, using on-chip through-reflect-line calibrations. We discuss the measured attenuation in terms of conductor losses in the bilayers and show to what extend the disturbance of the line geometry affects the microwave properties.
