    Abstract: An electronic device may include one or more radios and one or more antennas. Radio-frequency transmission lines may couple a radio to a corresponding antenna. To more efficiently form a radio-frequency transmission line, the radio-frequency transmission line may be formed from interconnected conductive traces distributed between a plurality of printed circuits. By integrating transmission line structures onto printed circuits that also serve other functions, the device can require less space to implement a radio-frequency transmission line. While one or more of these printed circuits may individually be unsuitable to implement a radio-frequency transmission line with a particular impedance, the composite impedance of these transmission line structures across the printed circuits, when properly configured, may provide a radio-frequency transmission line with the particular impedance.
