In preparation for the future characterization of the microwave properties of pulsed laser deposited high-temperature superconductor YBa2Cu3O6+x (YBCO) thin films, a YBCO growth optimization is performed using different substrate materials that have both a small dielectric constant and a small dielectric loss tangent. At first, the effect of thermal contact between a SrTiO3 substrate and the sample holder is investigated by comparing silver paste and amechanical attachingmask as fixing techniques. Hence, the thermal contact is observed to be a crucial parameter for successful growth, while the effect of lattice mismatch when using, e.g., MgO, SrLaAlO4, NdGaO3, and (LaAlO3)(0.3) (Sr-2 AlTaO6)(0.7), is seen to be less important. In addition, the preliminary reflection-type measurements for a meander-type coplanar stripline YBCO resonator are implemented and a comparison between the calculated and experimentally determined field-dependent frequency values is obtained.
