A signal transmission structure is provided. The signal transmission structure has salients. The salients are corresponding to the position of the non-reference region and protrude from a lateral side of the signal traces. When the signals are transmitted on the signal traces, the parasitic capacitance between the salients and the reference plane can improve the characteristic impedance mismatch. Hence, when the signals are transmitted in a high frequency/high speed environment, the salients of the signal transmission structure reduce the effect of the near-end and far-end crosstalk generated by the other signal trace when a signal trace passes through a non-reference region, in order to keep the good quality of the signals.
