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%。
