對於筆記型電腦而言，傳統內藏式天線設計大多僅能操作於無線區域網路，並無法提供無線使用者豐富且無縫隙的服務，為解決此問題，我們在本論文中提出了一系列可雙網或多網操作的內藏式天線設計，首先是提出一種結合雙天線元件的組合型天線，可雙網操作於WWAN/WLAN，接著我們使用了寄生元件增加操作頻寬，設計出一個可雙網操作於WLAN/WiMAX之短路單極天線。然而，為了達成縮小化的天線設計，我們提出了一種結合陶瓷天線及印刷輻射部的複合型天線，其可雙網操作於WLAN/WiMAX。接著我們提出一種可多網操作於WPAN/WLAN/WiMAX之寬頻短路單極天線且推廣應用至MIMO系統，最後我們設計出一項兼具縮小化與寬頻多網操作的耦合型天線，其尺寸大致為目前相同應用中最小的。

For laptop computers, the conventional internal antennas are usually used to operate in the WLAN system only, which can not provide sufficient and seamless services for wireless users. In order to overcome this problem, we propose some internal antennas having dual-/multi-network operation capability in this dissertation. Firstly, we present a combo antenna, which combines two shorted monopole antennas for operating in the WWAN/WLAN dual-network system. Secondly, we introduce a shorted monopole antenna through adding a parasitic element to enhance the impedance bandwidth for operating in the WLAN/WiMAX dual-network system. Thirdly, for achieving the compact-size antenna, we present a composite antenna which is composed of a ceramic chip and a printed radiating portion. Fourthly, we introduce a wideband shorted monopole antenna which can provide a wide bandwidth to cover the WPAN, WLAN, and WiMAX operations, and apply it to the MIMO system. Finally, we propose a coupling-type monopole antenna having multi-network operation capability and a compact size, which is about the smallest antenna for wideband operation in the laptop computer so far.
