dc.description.abstract | 本論文提出幾種部分反射面高指向性天線之設計,特別是著重在天線整體厚度之微型設計。此天線另外的好處是整體可印刷在多層電路板上,並且可利用陣列的方式實現增益之提升。我們提出兩種不同饋入機制的PRS天線,包含了微帶天線饋入以及槽孔天線饋入。我們的目標是提升整體天線增益以及槽孔效率。為了讓槽孔效率提升,我們增加PRS的面積並且利用2x2槽孔饋入激發,使得槽孔效率可達到50%,其天線增益在4.8GHz有12.8dBi。第二種則是增加PRS上金屬片的陣列個數來達成更高的增益,其天線增益在4.75GHz有13.4dBi。本論文天線整體厚度從傳統二分之波長縮小成三十分之一個波長。另外,我們也探究了此天線的部分反射板上可能具有行波模態的存在,加上末端會受到一定的反射量的影響而達成混波現象。因此我們改變末端的反射機制以探究天線的特性。第一種是將末端採取金屬條封閉短路,而第二種是末端改成漸進式的橢圓狀,兩者皆可使增益從原本的9.8dBi提升為10.9dBi,而後者更可進一步提升增益的頻寬從原本的18%增至23%。 | zh_TW |
dc.description.abstract | This thesis presents the design of Partially Reflective Surface(PRS) high gain Antennas, particularly with emphasis on the thickness reduction of the entire antenna. The advantage of the presented are the entire antenna module can be fabricated with low-cost Printed Circuit Board(PCB) and the element design can be extended to the array systems through a feeding networks for enhance of gain and aperture efficiency. Two types of feeding schemes are investigated, including patch-fed and slot-fed. For the aperture efficiency enhancement, the PRS antenna area is extended and fed by 2x2 slot-coupled microstrip lines, where the efficiency of 50% is achieved with peak gain of 12.8dBi at 4.8GHz. For the gain enhancement, the antenna is configured as arrays of metal strips that the peak gain of 13.4dBi is obtained. Additionally, the thickness of the entire antenna is reduced to thirtieth wavelength, compared to the traditional half-wavelength distance. At last, we investigate the radiating mechanism of the presented antenna, including the traveling-wave mode and the standing-wave mode due to the reflection from the edge of finite-size PRS .Through various treatments on the edge boundary, the gain may be increased from 9.7dBi to 10.9dBi and the bandwidth also improved from 18% to 23%. | en |
