摘要 毛细现象大约在200年前便断断续续被欧美学者所研究讨论，但由於当时微细加工受到仪器设备和制造精度的限制，因此发展极为缓慢；近年来由於微机电系统与微细加工之精进，许多具有微流道的应用设备，陆续被制作问世，加上光学显微镜与影像撷取设备的普遍，对於研究此课题的推展极有助益；且随著微生医、覆晶底胶充填与微流体系统等领域之受到重视，毛细现象导致的充填问题、驱动原理及液体流动的控制，都变得相当的重要；本研究基於如此的动机与目的，进行微流道内液体之毛细流动现象及时间的探讨。

A multiplayer chip LC resonator was fabricated using planar inductor and parallel plate capacitor. Because lumped inductor has small Q value and there is stray parameter effect in high permittivity substrate, the Q value of chip LC resonator is not high. Resonators based on λ/4 stripline with end short circuited were designed and fabricated. Input and output pads, coupled to the stripline using gap-coupling capacitor, are in the same layer with the center conductive strip. This new structure is very convenient for manufacturing in comparison with the conventional structure.

采用间隙电容耦合结构实现的谐振频率为1.8GHz四分之一波长终端短路带状线单端口谐振器的Q值最大值为225，谐振频率为1GHz双端口谐振器的Q值为83，谐振频率和Q值与耦合间隙、带状线的厚度和耦合引线长度有关；二分之一波长带状线谐振器的Q值和四分之一波长相比较尺寸较大，由于导电带较长，造成金属的损耗增加，从而导致谐振器的Q值较低；带状线结构的谐振器频率调节困难，本文提出了改变接地端的宽度实现谐振频率的微调方法，可实现频率调节量约1.5%。
