本論文是針對印刷槽孔天線之多頻特性進行分析與探討。其中所設計之天線皆採用50歐姆微帶線饋入方式,分別設計出一個三頻多邊形槽孔天線與雙頻矩形槽孔天線。首先提出一多邊形槽孔天線具有寬頻效果(1.85GHz~5.83GHz),接著在槽孔中央加入兩個長條金屬片分別來抑制兩個頻段,適當的選擇兩細長條金屬片之位置及長度,則可得到符合WiMAX應用之三頻多頻形槽孔天線。接下來,以寬槽孔天線為設計概念,設計出一矩形槽孔天線在高頻部份有良好匹配(4.475 ~ 5.825GHz),接著在矩形槽孔底部延著X軸插入一個長條金屬片匹配低頻之頻段(2.425 ~ 2.775GHz)。適當的選擇細長條金屬片之位置、長度及粗細,則可得到一雙頻矩形槽孔天線。
本論中不僅僅對良好的天線阻抗匹配有詳細的研究,在場形圖,天線增益也都有完整之討論。
The designs of printed slot antennas for multi-band have been investigated in this thesis. All the antennas are feed by a 50- microstrip line. We design the triple-band polygonal slot antenna and dual-band rectangular slot antenna respectively. First, we examined the polygonal slot antenna with a broadband effect (1.85GHz~5.83GHz). And, we inserted two narrow strips into the polygonal slot to rejected two bands. By properly choosing the length and location of the two narrow strips, the triple bands of WiMAX can be achieved. Next, based on the design of wide slot antenna, we design the rectangular slot antenna with a broadband effect (4.475GHz~5.83GHz). And, we inserted a narrow strip respect to the x axis into the bottom of rectangle slot antenna. This arrangement produces the low band (2.425GHz~2.775GHz). Combine the low band and the high band caused by rectangular slot to from a dual-band antenna. By properly choosing the position and location of the narrow strip, the dual-band antenna for WLAN application can be achieved.
In this thesis, we not only investigate the impedance matching of the antenna, but also radiation patterns and gain.
