摘要

這篇論文主要探討是將合成式左右手傳輸線應用於功率分配器，並且加入右手傳輸效應，使其達到寬頻九十度相位差的特性。將此左右手混合傳輸線利用集總元件的方式實現在積體化被動製程的低溫共燒陶瓷(Low Temperature Co-Fire Ceramic, LTCC) 中，並探討設計的流程。
我們利用佈局的調整，同時達到所需的元件有及其寄生元件的量，在積體化被動元件製程中實現了平衡態的寬頻左右手混合傳輸線，最後我們利用這個技巧設計一套相位差90度可應用於2GHz到4.2GHz的寬頻功率分配器。

The thesis is about the application of composite right/left-handed transmission lines (CRLH TL). The right-handed (RH) response is included in the design of broadband quadrature power splitter. Both CRLH and RH transmission lines will be implemented by lump elements on the low temperature co-fired ceramic, (LTCC) process.
We will realize desired lump element and its parasitic element simulaneously by adjusting its layout in LTCC process. A broadband balanced CRLH TL can be implemented using these lump elements. Finally, we will apply the design technique to realize a broadband quadrature power splitter (QPS) with phase error in and ±0.5dB amplitude mismatch from 2GHz to 4.2GHz.
