本論文根據現今小型化多媒體行動裝置的發展趨勢,提出多操作頻帶之平面式單極天線設計,並將天線分別應用在膝上型電腦、行動電話、USB無線網路卡三種不同行動通訊裝置的系統接地面上,也都能提出一因應的解決方案來達到適用於未來的WLAN (Wireless Local Area Network;無線區域網路) / WiMAX (Worldwide Interoperability for Microwave Access;微波存取全球互通)無線通訊系統規範,同時也能維持良好的輻射特性。
This thesis, on the basis of the development trend of present miniaturized multi-media mobile devices, proposes a uni-planar monopole antenna design for multi-band operations. This antenna can be installed on the ground surfaces of three different mobile communication systems: laptop computers, mobile phones, and USB wireless network cards. This design represents a unified solution to both WLAN (Wireless Local Area Network) and WiMAX (Worldwide Interoperability for Microwave Access) wireless communication standards. Antenna radiation characteristics were maintained excellent for the proposed antenna installed in all these three environments.
