    摘要: 本論文主要是設計並探討一可涵蓋長期演進(LTE700/2300/2500)及無線廣域網路(GSM850/GSM900/DCS1800/PCS1900/UMTS2100)八個頻段之手持裝置,參考市面上常見的手機尺寸,並定義整體空間大小為55x120mm²,其次考慮到實際組裝性,將天線尺寸定義為(55mm x 10mm x4.5mm³)進行設計。
    由於時下手持裝置等產品外觀設計多以輕薄為主,故此論文天線設計乃以一軟型電路板貼附在塑膠件的結構為設計方向,實際應用上採用成熟的印刷軟型電路技術方式製作天線線路,並將天線與塑塑膠件結合,完成天線單元,以目前成熟的天線廠與手機代工廠都具備在大量生產時保持特性的一致性與高良率。在設計天線低頻部分(LTE700/GSM850/GSM900),是藉由天線饋入點產生一λ/4的單極天線與接地端產生出寄生路徑所產生低頻寬頻結構,而高頻部分(DCS1800/PCS1900/UMTS2100/ LTE2300/LTE2500)則是在低頻兩個路徑上增加支流來增加高頻應所需要的1GHz頻寬的需求。詳細的天線設計模擬分析以及實作結果在本文中將一一介紹。
    ;. For the high-band portion(DCS1800 / PCS1900 / UMTS2100 / LTE2300 / LTE2500) of antenna, the proposed antenna was added trace attached on low band for tuning the high-band matching to achieve up to 1 GHz bandwidth demand. Detailed antenna designs and measured results are introduced in this thesis.
    This thesis mainly studies the long term evolution (LTE700/2300/2500) and wireless wideband network (GSM850/GSM900/DCS1800/PCS1900/UMTS2100) of handheld devices. Referring the size of mobile phone in the market, defining the overall space at 55mm x120mm, and further considering the workability of assembly in real use, the antenna size is defined at 55mm x 10mm x 4.5mm in this design. Due to the market trend of the mobile phone, the size is preferred to be light and thin. The design of the film antenna in this thesis is based on the printed circuit FPCB stick on the plastic material for the application of the mature skill and capacity of producing printed circuit FPCB. In order to complete the design of combination of the antenna and plastic from the huge market demand, this kind of antenna make itself high yield rate and quality consistence. In this antenna design at low
    frequencies (LTE700/GSM850/GSM900), it is to useλ/4 monopole which connected to the ground to generate parasitic trace; a wideband at lower frequencies. For high frequencies (DCS1800/PCS1900/UMTS2100/ LTE2300/LTE2500), it is to add partial current at 2 traces of low frequencies for the purpose of increasing 1 GHz which is required at high frequencies. Antenna design, simulation analysis, and practical test data will be will be given in each chapter.
