臺灣博碩士論文加值系統

本論文主要研究目標為：應用於無線網路卡的偶極天線之設計，所設計的天線主要為雙頻帶操作，操作頻帶為 2.4 GHz (IEEE 802.11b) 和 5.25GHz (IEEE 802.11a)，而這兩個頻段都是屬於無線區域網路 ( Wireless local Area Network, WLAN)的頻段。同時也討論並設計了在三頻帶操作的天線，除了無線區域網路頻帶外，再加上 1.8 GHz頻段，可增加應用在數位通訊系統(DCS)上。本文所設計的天線，都是將天線主體，直接印刷在玻璃纖維微波基板的相對兩面上，使得天線可以直接與微波電路相結合，增加了製作上的便利性，降低了製作成本。本論文分別提出了幾種設計方式，包含：具有蝕刻倒 L形狹縫之雙頻偶極天線、具有蝕刻一對倒 L形狹縫之三頻偶極天線、具有蜿蜒線之雙頻偶極天線，以及具有蜿蜒線和微帶電感之雙頻偶極天線，結果成效良好。

In this paper, most of dipole antenna is devised in dual-band operation for WLAN application. Some designs are developed in tri-band operation for DCS / WLAN bands. The dipole antenna is easily fed by a pair of parallel metal strips printed on the opposite sides of the dielectric substrate. The parallel metal strips are connected to a 50  microstrip line with a truncated ground plane. Several kinds of design, slited dipole antenna, meander dipole antenna.
