摘要

本論文對UWB系統之關鍵元件－天線，作論述及研製。文中已完成適用於UWB系統之各種規格，該天線為平面化的架構之設計，且為兩種不同極化方式的天線，分別為線性極化波及圓極化波。
此外也利用混合方式來設計且實作出適用於802.11a頻段之混合式天線。

關鍵字

In this thesis, the broadband design of antennas is the major achievement. Planar antennas are investigated and verified for ultra wide band（UWB）communication systems. Both linearly polarized and circularly polzarized antennas are designed and implemented.
In addition, a hybrid couple broadband antenna is presented. This structure can also be utilized for IEEE 802.11a applications.
