摘要

為了研究特異性材料的特性和複合式左右手傳輸線上應用方向，例如低通、高通、帶通和帶拒濾波器、無限波長天線等的設計，利用特異性材料的背波特性，縮小元件的尺寸和提升整體的性能，以達到手持式系統的應用。同時配合電磁模擬軟體和電路模擬軟體進行模擬和驗證，最後由傳遞距陣法和ABCD矩陣法進行特性的分析和證明。
利用新型的C型結構，成功的得到負導磁係數的特異性材料，並將此特性性材料應用在濾波器和天線上。為了獲得縮小化和寬頻特性的濾波器，本論文利用互補式分裂共振環的設計，達成寬頻帶通濾波器的設計，其成果可應用在WiMAX（2.3∼2.8 GHz、3.3∼3.8 GHz、5.2∼5.8 GHz）頻段內，並且證明在某些頻段內傳播常數為負值，以此說明特異性材料在特定的頻段下具有的背波特性。並且將負導磁係數遮罩應用在天線上，提供天線縮小化的方法。

The major purpose is to study the characteristics of metamaterials and apply to filter and atenna in this thesis.Using the characteristic of backwad wave to achieve small size and good performance for WiMAX（2.3∼2.8 GHz、3.3∼3.8 GHz、5.2∼5.8 GHz） bands applicaiotn. The softward of Ansoft High Frequency Structure Simulation and Advanced Design System were also be used in this thesis. Finnaly, using retrieve and ABCD matrix to improve the characteristics.
A C-shape structure that has the characteristic of negative permeability in specification freqency was proposed. The C-shape shell was applied to reduce the size of antenna and used to the complementary split ring was also proposed and applied to the composite right/left handed transmission line to achieve bandpass filter for WiMAX bands. The bandpasss filter has the 3 dB bandwidth from 2.1 to 5.9 GHz and has the characteristic of backward wave.
