本文研究了在印制电路板上存在局部不平衡的差分型微带线的平衡-不平衡转换系数(TCTL：横向转换传递损耗，TCL：横向转换损耗)和辐射发射。结果表明，在加入不平衡元件后，辐射发射随TCL的恶化而增大。用四端对网络链矩阵对TCTL和TCL的计算结果与测量结果吻合较好。为了计算差分型微带线的辐射辐射，利用四端对网络链矩阵计算了具有局部不平衡的差分型微带线上的共模电流。辐射发射的计算结果也与测量结果相吻合。
In this paper, a balance-unbalance conversion factor (TCTL: Transverse Conversion Transfer Loss, TCL: Transverse Conversion Loss) and a radiated emission for differential type microstrip lines with a partial unbalance on a PCB (Printed Circuit Board) are investigated. As the result, after inserting an unbalance element, it can be seen that a radiated emission increased according to the deterioration of TCL. The calculated results of the TCTL and TCL by using 4-terminal pair network chain matrix agreed with the measured results very well. In order to calculate radiated emission from the differential type microstrip lines, a common mode current on differential type microstrip lines with a partial unbalance was calculated by using 4-terminal pair network chain matrix. The calculated results of the radiated emission also agreed with the measured results.
