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.
