Planar superconducting resonators are now being increasingly used at mK temperatures in a number of novel applications. However, they are also interesting devices in their own right. We have experimentally investigated three types of niobium resonators fabricated on sapphire and SiO2/Si substrates. They all exhibit a non-trivial temperature dependence of the centre frequency and quality factor. Our results are consistent with the idea that the resonators are affected by the presence of two-level fluctuators in the substrate.
