本文提出了一个采用感性耦合的四分之一波长微带谐振器的小型化滤波器。四分之一波长谐振器之间的耦合是通过并联短路枝节实现，这个短路支节可以等效为一个K变换器。其优点是可以很容易地通过调节短路枝节的长度来改变谐振器间的耦合系数。在这篇论文里，我们展示了如何利用这种结构来设计和优化一个四阶滤波器。

This paper proposes a compact filter using inductive coupled quarter-wavelength resonators. The coupling between the quarter-wavelength resonators is realized by a short-end stub which behaves as a K-inverter. As a result, the coupling coefficient of the resonators can be easily controlled by the length of the short-end stub. A fourth-order filter is designed and fabricated to demonstrate the proposed method.
