A signal transmission structure is disclosed. The signal transmission structure is adapted for a circuit substrate, including at least a signal line, a plating bar and a reference plane. The plating bar is disposed on a side of the reference plane and connected to the signal line. In addition, the plating bar is disposed on the side of the reference plane, and the reference plane has a non-reference area corresponding to the plating bar. The signal transmission structure can reduce the impedance mismatch at the conjunction of the signal line and the plating bar, and the resonant frequency of the plating bar can be improved as to generate a desired transmission quality of the signal.
