本論文主要在探討槽線(Slotline)環形共振器結構特性，由於共振器的使用在電路上數量繁多，饋入耦合能量的方式也多有不同。因此本論文研究在槽線架構下，不同饋入方式在頻率響應上的影響。以等效電路模型為基礎，設計一系列的分析，逐步地推導出槽線環形共振器的架構，並藉由此等效電路模型，改善饋入方式和環形架構，實現具有環形共振器特性的平面電路。本論文中使用全波電磁模擬軟體IE3D和HFSS完成槽線環形共振器的設計，並使用電路模擬軟體ADS完成等效電路的設計，將電路實做於FR4基板上，經由比較模擬與實做的結果，確認設計的正確性。 In the thesis, the design of the slotline ring resonators is discussed. Due to a variety of resonators employed in circuit design, the feeding(or energy-coupling) strategy is always an important issue. Thus, different kinds of slotline feeds are discussed in the thesis. Based on the equivalent circuit models, we use a series of analyses to study the scheme of slotline ring resonators step by step. By analyzing the equivalent circuit models, we improve the feeding strategy and ring structure to realize a coplanar circuit which has the characteristic of ring resonator. The full-wave electromagnetic simulator, IE3D and HFSS, will be used in the design. The circuit simulator, ADS, will be used in the design of equivalent circuit model. Circuits will be realized using FR4 printed-circuit boards. The design will be validated by the comparison with experimental results.
