Abstract(in English) To provide basic considerations for the realization of method for suppressing the EMI from differential-paired lines, the characteristics of the SI performance and EMI of shielded-paired lines are investigated in this paper experimentally and by a numerical modeling. Firstly, transmission characteristics of TDR measurement and frequency response of |Sdd_<21>| are discussed, from view point of signal integrity. Secondly, as the characteristics of the shielding-effectiveness (SE) performance for EMI, frequency responses of electric and magnetic fields are investigated. Although placement of conductive shield near the paired-lines decreases characteristics impedance, |S_| for the "with 5.5μm-thickness copper shield" is not deteriorated compared with "without shield" and sufficient SE performance for both electric and magnetic fields can be established. But, thin-shield deteriorates both SI and EMI performances.
