| dc.description.abstract | 本篇論文使用極化分集及場型分集，設計一支涵蓋超寬頻(Ultra Wide Band, UWB)頻段的MIMO天線，頻寬達3.1GHz~10.6GHz。本天線結合一組寬頻的韋瓦第天線及寬頻的開槽天線，其天線增益在操作頻帶內皆在2dB以上。此外，為了解決無線區域網路Wireless Local Area Network (WLAN)在 IEEE 802.a的通訊協定中5150–5825 MHz 的頻帶和超寬頻之頻帶重疊問題，吾人在本天線設計中加入了5GHz~6GHz的頻帶阻斷設計(band-rejection)，以有效降低信號之間的干擾。經模擬和實際製作及量測，計算得到的天線間相關係數在0.1以下，而分集增益在4dB以上。本論文內並附上模擬和量測的結果以茲驗證。 | zh_TW |
| dc.description.abstract | This thesis presents MIMO (Multiple-Input Multiple-Output) antennas designed for Ultra Wide-Band. The antenna system includes a Vivaldi antenna and a rectangular aperture antenna.
Polarization diversity and pattern diversity are employed in this design. Antenna bandwidth covers from 3.1GHz to 10.6GHz. Antenna gain is larger than 2dB. In order to avoid the interference with wireless local area network (WLAN) of IEEE 802.a in the 5150–5825 MHz band, several frequency notch designs are included. The simulated and measured data are included with comparison. Some important parameters are simulated to verify MIMO performance. Correlation of the two antennas is below 0.1 and the diversity gain is greater than 4dB. | en |
