Characteristics of mode-conversion of bent differential-paired lines with different EM coupling

Abstract

In order to provide basic considerations for the realization of methods for suppressing the mode-conversion and EM radiation from differential-paired lines with length mismatch, the mode-conversion in bend differential-paired lines with different EM coupling was studied with FDTD modelling. It is demonstrated that the differential-paired line with thinner dielectric substrate which can maintain narrow width of trace, is suitable for improving the SI performance and suppressing the EMI.
