本論文提出三種共平面天線,操作頻段為WLAN(2.4GHz-2.485GHz和5.15GHz-5.85GHz)。
一開始先設計領結型單頻天線,操作頻段為5.08GHz-7.02GHz,再以此延伸第二種繞線式領結型天線,操作頻段為雙頻帶,2.28GHz-2.50GHz和5.03GHz-6.95GHz,最後以前兩種天線為基礎,達到縮小化雙頻帶天線,操作頻帶為2.26GHz-2.57GHz和4.81GHz-6.56GHz。

This research studied three planar antennas, operating in the WLAN frequency bands (2.4-2.485GHz and 5.15-5.85GHz).
In the first design, we have constructed a Bow-tie shape antenna, operating in the single frequency band of 5.08GHz-7.02GHz. Subsequently, we have modified the design to a second spiral shape Bow-tie antenna capable of operating in dual-band modes of 2.28GHz-2.50GHz and 5.03GHz-6.95GHz. Finally, based on our previous two Bow-tie antennas, a miniaturized dual-band antenna was designed. The final design exhibits not only the advantage of being more compact but also demonstrated a superior performance in the wider dual-band modes of 2.26-2.57GHz and 4.81-6.56GHz.
