本論文主要研究一個由共面波導饋入轉為方形螺旋槽線的天線,以及一個由共面波導饋入轉為斜角螺旋槽線的天線。我們使用套裝軟體Ensemble來設計天線的阻抗匹配以及輻射特性。
我們以共面波導饋入轉為槽線的雙極天線為基本設計的原理。利用螺旋槽線不同的長度及寬度,來達到想要的共振頻率及阻抗匹配。此天線包含了IEEE 802.11a以及IEEE 802.11b的頻段。其範圍為2.4~2.48GHz,5.15~5.35GHz和5.725~5.825GHz。
在最後,為了驗證此一共面波導饋入轉為方形及斜角螺旋槽線的天線設計,實際製作了一個共面波導饋入轉為方形及斜角螺旋槽線的天線和理論結果相比較。實驗結果證明此一天線之設計是可行且正確的。
The CPW-fed multi-band rectangular and oblique spiral slot antennas are studied in this paper. The input impedance and the radiation characteristics of these antennas are investigated using the software package Ensemble. In the design of the antenna, the slot dipole antennas are used as the basic unit.
Then different lengths and widths of the slots in the spiral slot are used to achieve the desired resonant frequencies. The antennas cover the IEEE 802.11a and b frequencies which are 2.4~2.48 GHz, 5.15~5.35 GHz, and 5.725~5.825 GHz.
In order to clarify our design, both the CPW-fed multi-band rectangular and oblique spiral slot antennas are designed and fabricated. Comparing the simulated and experimental results, these antennas are proved to be correct and practical.
