摘要

本篇論文是對於正三角形雙頻平面槽孔天線的特性進行頻率縮小化之設計與研究，以應用於IEEE 802.11a/b/g 無線區域網路，並將實際製作天線實體予以量測以驗證理論之正確性。此正三角形平面槽孔中的兩等腰邊崁入F型形狀的負載金屬片，讓金屬片影響電流路徑之影響使頻率縮小化，使其在高頻部分由原本的5650MHz降至5190MHz縮小比率為16.36%，在低頻部分由3650MHz降至2450MHz縮小比率高達55.11%，使得此三角形雙頻平面槽孔天線在Bluetooth及Wireless LAN有所貢獻。

By embedding properly two F-shaped strips at the side of the triangular slot antenna, a novel compact dual-frequency design is proposed and experimentally studied. With the use of F-shaped strip, the antenna size reduction for two operating bands can reach about 55.1% for 2.4GHz band and 15.4% for 5 GHz band. IE3D and Ansoft simulation software are used to identify with the measured results. Operating frequencies across the obtained lower and higher bands are of the same polarization planes. Details of the proposed broadband dual-frequency design are described, and experimental results of the constructed prototypes are presented and discussed.
