傳統的行動通訊天線內藏於筆記型電腦時，由於空間有限，天線的操作頻寬一般不足或是需要佔有較大的體積以滿足GSM/DCS 系統的操作。為了克服此一問題，在本論文中我們成功地設計出三種創新的行動通訊天線，除了可多頻操作，也適合內藏於筆記型電腦中。首先，提出一具有寄生短路元件的單極天線設計，可達成GSM900/DCS/PCS/UMTS頻帶的四頻操作；接著，為了能再涵蓋美洲地區所使用的GSM850頻帶形成五頻的操作，提出一具有短路結構的寬頻單極天線設計；最後，提出一具有寄生短路元件之開迴路天線設計，除了其縮小化的尺寸之外，該天線的頻寬範圍亦可涵蓋GSM850/GSM900/DCS/PCS/UMTS系統的五頻操作。詳細的天線設計及實驗數據將在本論文中說明及討論。

When the conventional mobile communication antennas embedded in the laptop computers, it is difficult to achieve enough bandwidths or a larger antenna size is required for covering the GSM/DCS operation. To overcome this problem, three new mobile communication internal antennas, having multi-band operation capability and suitable to be embedded in the laptop computers are proposed. At first, we introduce a monopole antenna with a shorted parasitic element. This antenna can provide wide bandwidths to cover GSM900, DCS, PCS, and UMTS operations. Then, in order to additionally achieve the GSM850 operation to form the penta-band operation, we present a wideband monopole antenna with a shorted structure. Finally, we propose an open-loop antenna with a shorted parasitic element. The antenna occupies a smaller volume and is capable of providing wide bandwidths to cover GSM850, GSM900, DCS, PCS, and UMTS operations. Detailed antenna designs and experimental results are presented and discussed.
