摘要
本論文主要在探討微帶線環形共振器結構特性，進而設計出不同的饋入方式。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，且對於縮小面積上卻相對地較少提及。因此本論文選擇一較佳之饋入方式並同時改善製作上所使用的面積大小。本文中使用電磁模擬軟體IE3D完成微帶線環形共振器的設計。針對不同參數的改變，探討對電路造成的影響，並以FR4基板實現。經由比較模擬與實作的結果之後，確認設計的正確性。

Abstract
In the thesis, the design of the microstrip ring resonators is discussed, and new feeding strategies are proposed. Due to a variety of resonators employed in circuit design, the feeding(or energy-coupling) strategy is always an important issue. Thus, a better coupling strategy will be applied and the size of the circuit configuration will be improved at the same time in the thesis. The full-wave electromagnetic simulator, IE3D, will be used in the design. Circuits will be realized using FR4 printed-circuit boards. The design will be validated by the comparison with experimental results.
