本論文以平面單極天線作為基礎,主要應用於內藏式天線設計,符合市面上第二代與第三代行動通訊系統所需之要求,並且涵蓋GSM850/900/DCS/PCS/UMTS/WLAN/WiMAX多頻段操作,便利於無線數據傳輪與語音影音服務。
在第二章論文所提內藏雙臂單極手機天線,是利用單極天線原理與蜿蜒機制複合式設計概念,整合高低頻雙路徑,達到可適度縮小天線空間內藏天線手機天線目的。第三章雙網單極天線設計機制是採用單路徑蜿蜒方式,達到單路徑多重共振效果。本系列天線設計將與系統主機板整合,以簡化製作,降低成本。且所設計天線皆能達到高輻射效率、體積小及增益變化量穩定之要求,並實際考量手機內部之空間,以滿足現今手機多功能性與高相容之目標,是非常具有商業應用的價值,並且足以包涵目前各國所使用的手機頻段。
最後,並探討各天線設計在天線結構參數變化對本系列天線所造成之影響,以及結論綜合比較。
In This thesis, an internal planar antennas for multiband mobile phone applications are presented. Based on the characteristics of monopole antenna, multi-band, and uniform radiation fields can be achieved. In Chapter 2, “Internal two-arm antenna for multi-band mobile phone” with five operating bands ( GSM/DCS/PCS/WLAN/WiMAX) is presented. The other antenna is suitable for mobile handsets on the 2G, 3G and with five bands ( GSM/PCS/UMTS/WLAN/WiMAX) operation, which is presented in Chapter 3. These proposed antennas have a simple structure, easily fabricated and low cost. They are also applicable for the further mobile communication systems.
