本論文主要是提出應用於行動手機上之多頻晶片天線設計，文中提出三款使用於直立式手機之多頻天線與其延伸性整合式設計，且應用介質材料做為晶片之基底來幫助天線設計更微型化、簡單化。相較傳統晶片天線，大多以單頻或雙頻設計應用於GPS或WLAN等通訊系統之頻帶，鮮少應用於行動通訊頻帶上，本論文所提出不同天線類型，藉由單極天線和迴圈天線的設計推廣至晶片式的天線外型設計，並使得晶片體積小於0.8立方公分，甚至小至0.3立方公分，並且可以在晶片天線附近整合如相機鏡頭與揚聲器等電子元件而不大影響天線輻射特性，進而達成基本通訊頻帶GSM850/900/1800/1900/UMTS之操作，甚至可進一步包含WLAN與WiMAX頻帶之通訊系統，相當符合未來行動手機應用之需求。

In this thesis, the study mainly focuses on developing multiband chip antennas for mobile handsets. Three possible solutions and their extended and integrated designs are presented. By using the dielectric material as the chip base, the chip antenna can be smaller in size and simpler in design. Most of the applications of the traditional chip antennas are rarely used as the mobile phone antenna and are commonly designed with a single operating band to cover GPS or WLAN operation only. Different types of the antennas are proposed in the thesis. The metal patterns of the monopole and loop antennas are manufactured inside the chip base with an occupied volume of generally less than 0.8 cc, some even as small as 0.3 cc. Electronic components like the lens of the embedded camera and the speaker can be integrated close to the chip antenna with little influences on the radiation characteristics. Consequently, the developed chip antennas are suitable for mobile communications and can cover not only GSM850/900/1800/1900/ UMTS bands but also WLAN/WiMAX bands.
