| dc.description.abstract | 本論文目的是針對可適用在802.11a頻段的高增益天線加以研製。文中採用了偶極陣列天線和螺旋天線兩種具有高增益特性的天線，了解其輻射機制後加以設計，比較兩種天線的優劣，並將實驗結果與HFSS及IE3D全波模擬軟體的模擬結果互相比較，最後藉由改變螺旋天線中的介電質特性來提高天線的增益。 | zh_TW |
| dc.description.abstract | This paper focuses on the design and implementation of high gain antennas. In this paper, dipole array antenna and helical antenna with high gain characteristic are adopted and designed. Measured data compared to HFSS and IE3D simulation is also presented. Finally, the gain of helical antenna is increased by using a novel technique. | en |
