Abstract
The integrity of circuit board signals is largely influenced by the far end crosstalk among microstrip lines. To research the far end crosstalk-reduction method, the methods of RSR structure and adding dielectric layer are specifically researched in this paper on the basis of Ansoft HFSS software simulation software by building the microstrip line model and comparing the influences of crosstalk in different guard line situations. According to the S41 parametric variation curve obtained, the influences of the number of geometric parameters of metal patch in RSR structure on reducing the far end crosstalk are discussed. In addition, the influences of the thickness of the dielectric layer added above the microstrip line and the relative dielectric constant of material on reducing the far end crosstalk are also discussed.
