本文中提出用於行動裝置的複合式多頻段天線設計，其設計使用不同的單極天線結構，組成三款小型、結構簡單、多頻操作之單極天線，成功的驗證此天線設計具有實際應用價值；此天線設計，不僅能克服頻寬不足的問題，在輻射效率特性方面，可以滿足業界實際使用時所要求的規範。複合式平面單極天線和複合式立體單極天線可涵六個應用頻帶GSM850/900/1800/1900/UMTS/ISM 之寬頻操作，天線輻射效率也均可達到
50%以上；USB dongle 天線可涵二個應用頻帶ISM/WiMAX 之寬頻操作，天線輻射效率均可達到60%以上。

In this thesis, we have proposed a compound multiband antenna design for portable devices. The designs are composed of different monopole antenna models to composition small size, simple structure, multi-band operation of the monopole antenna for the mobile devices and USB dongle. The advantages of the proposed antennas overcome the problem of insufficient bandwidth and meet the radiation efficiency of the industry standards. The used designs of compound multiband antennas can cover the wide-band operation of GSM850/900/1800/1900/UMTS and ISM/WiMAX, respectively. Above all, the experimental results show that the radiation efficiencies of the proposed antennas are more than 50% and satisfy the requirements of industry standards.
