Abstract: A serpentine guard trace for reducing far-end crosstalk of a micro strip transmission line is provided. The serpentine guard trace reduces receiving-end crosstalk caused by an electromagnetic interference of a signal of a nearby transmission line when transmitting a high speed signal through a micro strip transmission line on a printed circuit board. The serpentine guard trace is located between two nearby transmission lines and has a line width narrower than that of transmission lines for an effective serpentine structure. A characteristic impedance of the serpentine guard trace increases due to the narrow line width. Termination resistors having impedance which is the same as the characteristic impedance of the serpentine guard trace are located on both ends of the guard trace to minimize a reflection wave generated in the serpentine guard trace. The receiving-end crosstalk can be effectively reduced by using the serpentine guard trace instead of a linear guard trace.
