| Summary: | 碩士 === 中原大學 === 電子工程研究所 === 107 === This paper investigates on generation and mitigation of common-mode noise for bend discontinuities of differential transmission lines in microstrip line and strip line structure. This paper provides methodology to mitigate common-mode noise. The structure in frequency domain simulated by 3-D full-wave simulator HFSS and in time domain simulated by simulator ADS. In frequency domain compared by differential-to-common mode conversion, in time domain measured by common-mode noise. The mitigation scheme provided in this paper is that using trapezoidal compensation structure which can reduce common-mode noise
to increase transmission lines length. The design of trapezoidal compensation structure and structural dimensions are also a major focus of this paper. Analyze the impact of different parameters on common mode noise. Finally, the trend chart is sorted out.
