Resonators are at the core of many Penning trap experiments. They can be used to cool and detect trapped ions. This contribution presents a planar resonator design, using the high-temperature superconductor YBCO, allowing the resonator to be used in a LN2-cooled environment. Furthermore, the geometrical simplicity increases the reproducibility of this design. For frequencies in the range of 5-30 MHz, typical for the cyclotron motion of highly charged ions in a Penning trap experiment, this design is much smaller than previous toriodal resonators. Here, first results of these new types of resonators are presented.
