本論文提出了應用於寬頻以及三頻WiMAX之小型化印刷槽孔天線以及應用於WLAN之小型化單極天線,首先針對印刷槽孔天線的特性來分析與探討。為了考量到應用面,我們設計了一個主體為30 mm × 40 mm的小型化槽孔天線,其架構簡單且具有寬頻特性(2.17 ~ 6.25 GHz),接著在槽孔中央加入一長條金屬片來抑制不必要的高頻頻段以及在槽孔上方蝕刻一U型槽縫來抑制不必要的低頻頻段,當選擇了合適的參數則可得到符合WiMAX (IEEE 802.16d)應用之多頻段小型化印刷槽孔天線。接下來,小型化單極天線部份,設計一耦合饋入來激發接地面共振出低頻(2.39 ~ 2.52 GHz),再利用另一路徑共振出高頻(4.98 ~ 6.07 GHz),這種雙路徑的設計方式可設計出符合WLAN (IEEE 802.11a/b/g/n)之雙頻天線,使其涵蓋整個無線區域網路的應用。
Designs of the compact slot antenna for broadband operation and tri-band for WiMAX application and the compact monopole antenna for WLAN application are proposed in this thesis. The size of the compact slot antenna is only 30 mm × 40 mm, and the broadband antenna consists of a microstrip-fed line, and a wide rectangular slot with a reverse L-shape slot. It can resonate to the bandwidth from 2.17 to 6.25 GHz and about 97% determined by 10 dB return loss. In order to remove unwanted bands, so we used two methods to reject the bands. Inserted a strip in the slot of the broadband antenna, to reject higher frequency from 4.13 to 4.95 GHz and etched a U-slot up on the top part of the broadband antenna, to reject lower frequency from 2.96 to 3.17 GHz. Another case, the compact monopole antenna used a specified ground to resonate the low frequency and used a patch to resonate the high frequency. The compact monopole antenna has a low band of 2.39 ~ 2.52 GHz and a high band of 4.98 ~ 6.07 GHz for WLAN application.
