| Abstract(in English) | The authors proposed a model to evaluate common-mode excitation on a printed circuit board with signal lines with narrow ground plane. The model is called the "imbalance difference model". In this report, the model is applied to a set of test boards each of which has two symmetric microstrip lines that are excited with a hybrid balun, and the effect of thickness of dielectric is investigated and compared with measured results. Calculation based on the conventional "ground inductance model" is also performed, and results are compared. The estimated values with both methods and measurement results are in good agreement within 3 dB. |
