    Patent number: 4864280
    Abstract: A flexible carrier having on both opposite surfaces thereof foil films forming conductor tracks as inductance coils insulated from each other by the carrier. Each track is connected at opposite ends to a conductive region of the foil film to form electrodes for two capacitors establishing one resonant circuit. The coil forming tracks on opposite side surfaces of the carrier are arranged to accommodate relatively large capacitor electrodes of substantially equal dimensional area.
