本篇論文提出交互耦合與直接耦合兩種耦合的方式，設計出螺線型諧振器的新結構，俾供設計帶通濾波器時，達成提升耦合效率的目的。設計的螺線型諧振器，有習知的螺線結構，與以希伯特碎形結構為改良式圖型等，同時逕以比較其特性。其中，以簡化螺線型諧振器與簡化希伯特螺線型諧振器，能達到縮小面積、增加頻寬為目的。
在簡化螺線型諧振器中，得到的特性有，-0.3 dB低注入損耗，-27.1 dB高衰減量與較寬的頻寬29.1 %等。在簡化希伯特螺線型諧振器中，呈現的特性為，-0.27 dB低注入損耗，-19.5 dB衰減量與更為增寬的寬頻50.9 %等。文中，以電流分佈與頻率響應，為設計與分析的方法。

Both cross-coupled and direct-coupled configurations of the alternative spiral resonators are introduced with the large coupling coefficient for the bandpass filter design in this paper. The proposed spiral resonators included the conventional spiral resonator and the improved spiral resonator with Hilbert fractal configuration are studied and compared. In practice, the simplified spiral resonator and the simplified Hilbert spiral resonator present the performance of size reduction and bandwidth enhancement.
For simplified spiral resonator, the results with low insertion loss (-0.3 dB), higher out-of-band rejection level (-27.1 dB) and wide band filters (BW, 29.1 %) are obtained. For simplified Hilbert spiral resonator, the performance of lower insertion loss (-0.27 dB), high out-of-band rejection level (-19.5 dB) and wider band filters (BW, 50.9 %) are achieved. The results included electric current distribution and frequency responses are used for design and analysis.
