CONCLUSION
This paper proposes a method to
reduce far-end crosstalk based on TL-shaped DMS. This method designs a
TL-shaped DMS with a relatively simple structure and easy practical
application. Under the joint verification of theoretical analysis,
simulation verification, and physical test, TL-shaped DMS can improve
the insertion loss of adjacent microstrip lines while ensuring the
transmission ability of the etched microstrip lines, and the far-end
crosstalk can be well suppressed with a maximum reduction of 42dB.
Compared with other methods, The TL-shaped DMS proposed in this paper
has a simple design structure, does not occupy the original wiring
space, has the potential for universal application, and far-end
crosstalk was suppressed more significantly. However, its promotion and
application in a wide range need further research.
