We report the fabrication of a capacitor-shunted Josephson junction and its use as a microwave device with improved coupling to microwave fields. The junction was evaporated on a thin plastic substrate which was subsequently folded like a flat-spring clip in order to make a circular coupling loop terminated by a parallel-plate capacitor. The capacitor short-circuits the loop for high-frequency currents but keeps it open for dc currents, rendering possible the application of dc bias to the junction. The folded junction was observed at X band to couple 20 dB better to rf power than the same junction extended flat.
