| Abstract(in English) | In this paper, for reducing conductive noise currents from electronic equipment for vehicles, we made a simulation and experiment on how ground patterns affect the noise currents from three-layer printed circuit boards (PCBs) with slit-type and plane-type ground patterns. As a result, we confirmed that the crosstalk between two traces perpendicularly fabricated on the PCB with the slit-type ground patterns increases with the slit width. For the PCB with plane-type ground patterns, on the other hand, both the simulation and examination showed that resonance phenomenon occurs at unexpected low-frequencies. A circuit analysis revealed that the above phenomenon can be caused by the imbalance of a bridge circuit consisting of the trace circuits on the PCB. |
