Abstract :
In this study, the influence of the location of a ground plane on the induced noise (crosstalk) on a twisted-pair-wire (TPW) by parallel lines is experimentally and theoretically discussed by paying attention to capacitive coupling between the TPW and the parallel lines. The capacity is obtained by applying the finite element method (FEM) to the calculation of electric field intensity. It is confirmed that calculated results are in good agreement with experimental results within 1 dB. It is concluded that the closer the TPW is to ground plane, the smaller the induced noise on the TPW becomes
