BCB製程上傳輸線特性之研究

Abstract

本論文以一種新的傳輸線架構-挖槽的半同軸纜線為基礎，實作於環苯丁烷的材質上。並同時與微帶線及半同軸纜線作比較，探討其單端與差動對時的損耗優劣及其他特性，並研究此種架構與微帶線對於傳輸線的耦合現象之優劣。模擬及量測結果的顯示，在相同的線寬下，開槽線具有較低的損耗，在差動情況下，模擬結果則未顯示有明顯的差異。

This work is based on a new structure of transmission line- slotted semi-coaxial line and made on BCB substrate. We compared attenuation constant and other properties with microstrip line and semi-coaxial line in single-ended and differential mode. We also compared the coupling effect between proposed transmission lines and conventional microstrip line. The single-ended slotted semi-coaxial line shows lower attenuation constant by simulation and measurement under same line dimensions. However, differential slotted semi-coaxial line does not show clear improvement in attenuation constant.
