In Japan, a power-line communication (PLC or PLT) system was approved only as an in-house system. One of concerned matters is leakage electromagnetic fields from power lines, which are mainly caused by common-mode currents. The common-mode current should be estimated under a condition of LCL (Longitudinal Conversion Loss) of 16 dB in the Japanese rule. In this paper, the characteristics of LCL are...
A method for the analysis of crosstalk between two microstrip lines in arbitrary directions lying on different layers is proposed using a circuit-concept approach. Electromagnetic fields in a PCB substrate due to microstrip lines are estimated by using an image method and then those are applied to transmission line theory. To verify the proposed approach, we compared the results of our approach with...
The crosstalk of two bent transmission lines of arbitrary directions have been analyzed by a circuit concept approach. The results for the circuit concept approach, HFSS and measurements are in very good agreement. The derived equations can be expected to be easily applied them for analyzing crosstalk of a various kind of bent transmission lines in printed circuit board
