| Abstract(in English) | The bend in a pair of differential lines on printed circuit boards causes the path difference, which leads to the phase difference in signal propagation on each signal line and then results in mode conversion. This paper proposes a bend structure to suppress differential-to-common mode conversion by modifying the tightly coupled tapered bend so that the asymmetrical taper cancels the path difference remained at the tightly coupled bend. As a result, the amount of mode conversion was reduced by approximately 23 dB compared to the symmetrical taper. In addition, the reflect ion on differential mode was reduced by approximately 10 dB because the two-section asymmetrical taper can make the differential-mode characteristic impedance almost constant. |
