Summary :

In this study, the influence of the location of ground plane on the noise (crosstalk) induced on twisted-pair-wire (TPW) by parallel wire is experimentally and theoretically discussed by paying attention to the capacitive coupling between TPW and parallel wire. The capacitance is obtained by applying the finite element method (FEM) to the calculation of electric field intensity. It is confirmed that the calculated results are in good agreement with the experimental results within 0.5 dB. It is concluded that the closer the TPW is to the ground plane, the smaller the induced noise on the TPW becomes.
