dc.description.abstract | 本論文首先探討一維漏溢波天線末端的反射相位對整體天線造成的影響,並利用HFSS和MATLAB模擬軟體來比較天線在不同長度之下,末端開路或短路對天線指向度的差異。本論文利用一個微帶天線饋入、FR4之印刷電路板製作,厚度只有六十分之一波長的部分反射面高增益天線當作初始設計,將長形金屬片做末端處理來改變末端的反射相位,證實能有效地提高天線的實際增益,在頻率為5.28 GHz時從原本的9.0 dBi到10.4 dBi;而在金屬片週期性方向之末端做處理,亦可讓實際增益提升到10.0 dBi。接著將原本天線的四個角切除,在盡可能維持實際增益不變下縮小面積,藉以提高天線槽孔效率,可達50.84%。最後利用陣列微帶天線饋入來提高增益,天線在操作頻率5 GHz下實際增益有12.6 dBi,同時槽孔效率達到43.20%。 | zh_TW |
dc.description.abstract | The effects of the reflection phase of a 1-D leaky-wave antenna have been discussed at the beginning of the thesis. Using HFSS and MATLAB simulation, we compared the antenna directivity between the open and short termination for different length leaky-wave antennas. Based on a patch-fed partially reflective surface high gain antenna, fabricated on FR4 printed circuit board with only a sixtieth of wavelength thickness, the optimal edge reflection design at the strip end can effectively improve the realized gain up to 1.4 dB (from 9.0 dBi to 10.4 dBi) at 5.28GHz. On the other hand, optimizing the edge reflection at the periodic direction of metal strips can also improve the realized gain up to 10.0 dBi. By truncating the corners, the PRS antenna may also reduce the size, and therefore improve the aperture efficiency to 50.84% while maintaining the realized gain. Lastly, using the patch-fed array can reach the realized gain to 12.6 dBi at 5GHz while maintaining the aperture efficiency around 43.20%. | en |
