| dc.description.abstract | 本論文主要研究適用於各頻段的手機天線，內容將以槽孔天線為主。此架構是利用上層的微帶線饋入激發下層的數個蜿蜒槽孔造成多個共振頻率點而達到寬頻的需求。適用的頻段涵蓋GSM850/900、GPS、DCS1800、PCS1900 、 3G(WCDMA/CDMA2000)、Bluetooth、WiMAX、IEEE802.11a/b/g，並且針對手機天線應用上會遇到的各種重要參數做了模擬與討論。本論文的後半段，提出了一寄生接地天線，此架構是利用上層金屬之驅動元件去激發下層共振的部位，且利用殘段匹配的效果讓窄頻的單極天線也能達到寬頻的效果。接著對前面的手機天線在WiMAX頻寬上的缺失做了改良。最後，我們以此改良架構配合寄生接地天線去設計一分集手機天線，並分析其效能。 | zh_TW |
| dc.description.abstract | This thesis presents several novel designs of the slot antennas with applications for handset terminals in mobile communication systems. Fed by a microstrip line, the antenna uses the microstrip line on the top layer to excite the meander slot on the backed layer, the antennas perform multi-band resonances with sufficient bandwidth covering the following frequency bands of communications ( GSM850/950 , GPS , DCS1800, PCS1900 , 3G, Bluetooth , WiMAX , IEEE 802.11a/b/g)，several parameters are selected for investigating the working principles. In the second half of this thesis, a grounded parasitic antenna is presented. Fed by a microstrip transmission line, the antenna contains a T-shaped driven grounded parasitic element on the bottom layer, the open stub matching structure let narrow band monopole antenna can also achieve wide band performance. In addition, we improve the antenna bandwidth at WiMAX band and combine the structure with T-shaped driven antenna with open stub matching as a diversity antenna for further MIMO analysis. | en |
