本文提出小型化Wi-Fi雙頻天線,符合目前世界各國針對Wi-Fi開放之頻帶,頻帶範圍為Wi-Fi 2.4GHz (2400MHz~2483.5MHz)、5GHz (5150MHz~5850MHz)。本文提出的天線採用單極天線為基礎架構,並使用共平面波導及十字型的饋入方式,以改善單極天線的頻寬,天線架構芯線為高頻路徑,地線為低頻路徑,成功設計出高增益雙頻天線,並且利用非對稱式地線架構、頂端加載和寄生元件這三種設計法則,使頻寬得以涵蓋Wi-Fi完整的操作頻帶。運用Ansoft HFSS進行模擬及天線實作驗證,分析天線各部份變化之結果,完成了本文所提出之非對稱十字型饋入雙寬頻天線。
In this paper, a miniaturized Wi-Fi dual-band antenna is proposed, which is suitable for Wi-Fi 2.4GHz (2400MHz ~ 2483.5MHz) and 5GHz (5150MHz ~ 5850MHz) for Wi-Fi in the world. In this paper, the antenna is based on monopole antenna, and uses the coplanar waveguide and the cross-feed mode to improve the monopole antenna bandwidth. The antenna structure core wire is a high frequency path and the ground wire is a low frequency path. High-gain dual-band antenna, and the use of asymmetric ground structure, the top load and parasitic components of the three design rules, so that the bandwidth to cover Wi-Fi complete operating frequency band. Ansoft HFSS is used to simulate and verify the antenna implementation, and the results of the variations of the antenna are analyzed. The asymmetric cross-fed double broadband antenna is presented in this paper.
