Extracting CAD models for quantifying noise coupling between vias in PCB layouts

In this work, the metaljlled via holes are constructed into fences between the non-parallel microstrip lines to control the crosstalk. In practice, coupling between non-parallel traces is common. On the other hand, via holes are easy and inexpensive to buildusing the current fabrication process for the commonly used PCBs. The effects of the via holes for alleviating the coupling are investigated experimentally and numerically. The crosstalk is controlled by adjusting the position of the via holes, the structure of via fence, and the length of the via fence. Some design guidelines for the proper placement of the via holes are concluded. Experimen fs are conducted and the calculated results are compared with the measured data.
