臺灣博碩士論文加值系統

本論文分為兩部分，第一部分以基板合成波導之型式，實現一雙頻帶左右手漏波天線結構，能量由波導上方之開槽結構輻射，另於漏波天線兩端設計不同於波導結構之右手傳輸線，使雙頻帶設計更具彈性且面積縮小。於開槽旁增加貫孔(VIA)之設計，調整操作頻帶，並以雙開槽之型式提高天線增益。以上三種天線結構之設計理論與細節，模擬與量測驗證，於本論文第二及第三章中討論。
第二部分為低溫共燒陶瓷製程下，V頻帶端射型天線特性驗證，分別設計單極及槽孔兩種不同形式之天線，考量製作過程變異性，分析不同設計參數對於反射係數之影響，並對天線隔離度進行探討，模擬與量測驗證結果，於本論文第四及第五章中比較分析。

This thesis is divided into two parts, the first part is a design of CRLH dual band leaky wave antenna by substrate integrated waveguide (SIW). Energy is radiated from the top slots of the SIW. By adding transmission line differs from SIW structure on both sides of SIW, the dual band design can be more flexible and the size of antenna can be reduced. VIAs are added near the slot for adjusting the operating frequency. Dual slots on the top of SIW for enhancing the gain of antenna is also proposed in this thesis. Design theory, antenna structure, simulation and measurement verification of these three antennas, are discussed in the second and the third chapter in the thesis.
The second part is the verification of embedded end-fire antenna in LTCC for V-band. Two different type of antenna, monopole and slot, are proposed. Considering the variation in the manufacturing process, the impact of different design parameters on the reflection coefficient and the isolation are analyzed. The comparison of simulation and measurement result are discussed in the fourth and fifth chapter.
