構造による差動線路のクロストーク抑制の一検討(卒論・修論特集)  [in Japanese] A study on Suppression Crosstalk of the Parallel Transmission Line by Structuires  [in Japanese]

Abstract

1GHzを越す高周波帯で用いられる差動伝送線路では,信号線路間でクロストークが生じており,その抑制が求められている.本研究では,多層構造の異なる基板,ならびに差動線路間隔を離した基板におけるクロストークの抑制効果を実験とFDTD法によって解析した.多層構造の異なる基板での計算結果によるS_<21>,ならびに遠端クロストークは実験結果と傾向が一致した.strip構造の遠端クロストークはmicrochip構造よりも抑制された.差動線路間隔を離した線路でのクロストークは,microchip構造のクロストークよりもstrip構造では20dB以上の抑制効果が得られた.strip,shield線路周辺に電界が集中し,金属板により広がりが押さえられていることがFDTD解析より明らかとなった.strip構造では,線路幅を離すことでより効果的にクロストーク抑制が可能であることが明らかとなった.

The suppression of the crosstalk between parallel transmission lines is requested over 1GHz band. In this study, the suppression effects using two type models, such as the four kinds of the multi layer structuires and different distance between lines, are analyzed by experiments and FDTD method. The characteristics of S_<21> and far end crosstalk at multilayer structure by the analysis are cointed with those of experiment. The peak value of the far end crosstalk of the strip structure can suppress than that of microstrip structuire. When the distance between signal lines is farther, the far end crosstalk of the strip structure can suppress over 20 dB than that of the microstrip structure. Since the electric field is focused on the single lines at the strip and shield structure by the FDTD analysis, it is appeared that conductive plate can control for the extensity of the electric field. As the distance between signal lines of the strip structure is farther, the suppression crosstalk can be possible more effectively.
