| Abstract: | The impact of PCB dielectrics on transmission line when the high frequency signal travels through the PCB is described and discussed. Furthermore, a new PCB dielectrics parameters calibration process is proposed. It collects the design data by simulation and validation based on PCB test board, then it gets the Dk and Df using this new proposed process. The test results demonstrate that such process is effective and can improve the model accuracy of transmission line. |
