本論文針對2.4 GHz、WLAN以及WWAN之應用頻段分別設計四款微型化天線,其不僅體積小,且輻射效能佳,並可內建於射頻模組以及筆記型電腦中,具有高度的商業價值。第一款為操作於2.4 GHz之微型化倒L晶片天線並搭配匹配電路來提高天線之電氣性能。第二款為微型化倒F晶片天線,操作頻段為2.4 GHz,其利用平板式倒F天線架構並搭配短路腳控制輸入阻抗,使天線達到較佳的電氣性能,且上述兩款設計皆不需要任何的天線淨空區,有助於減少電路板之浪費以及提高模組內其他電路佈局之自由度,達到最小化模組開發。第三款天線為應用於WLAN頻段之微型化倒F天線,利用倒F天線架構搭配多重共振路徑並經由短路腳控制輸入阻抗,藉此激發多組共振而產生較寬的操作頻寬以符合WLAN應用頻段之需求。最後,第四款天線為適用於WWAN頻段之微型化倒F天線,採用正背板之佈局方式產生多重共振路徑而激發多組共振以達到寬頻的響應,其工作原理與第三款天線相似。本論文所提出之四款天線不僅體積小且輻射效能佳,而基板皆使用低成本之FR4搭配印刷電路板技術,因此可以有效地降低成本以及製程之困難度,適合內建於射頻模組以及筆記型電腦中,具有高度的商業價值。
This thesis proposes four kinds of miniature antennas for 2.4 GHz, WLAN (Wireless Local Area Network) and WWAN (Wireless Wide Area Network) applications, respectively. All of four antennas have a compact size and good radiation performance so that can built in RF module or laptop computer and suitable for commercial applications. The first design is about an inverted-L chip antenna using match network to improve the antenna performance which operating frequency is 2.4 GHz. The second antenna design is miniature planar inverted-F chip antenna for 2.4 GHz operation. It is based on a planar inverted-F structure and using shorted pin to adjust the input impedance, so that can optimization the antenna performance. Both antennas does not require any empty space so that can reduce waste and improve layout space of another circuit in the RF module. Using this antenna design can achieve minimize development of RF module. The third design is inverted-F antenna for WLAN application. This antenna using planar inverted-F structure and multiple resonance paths to excited more than one resonance frequency, therefore the antenna has a wide bandwidth for WLAN application. The final design is inverted-F antenna for WWAN application. It is similar to third design but the radiator is layout on different plane in the same PCB. Consequently the proposed designs fabricated on FR4 substrate to lower cost so that can integration into RF module or laptop computer and suitable for commercial applications.
