| 中文摘要 | 本文中設計一款新型共面波導饋入四矩形環多功能微帶天線。其架構是以四個方形環輻射貼片、兩個直角三角型的接地面及漸變形共面波導饋入微帶線所組成。此天線利用方形槽孔的矩形環輻射貼片使其產生多頻段之共振頻率,並以調整共面波導饋入微帶線寬度、微帶線與接地面之間間距及雙對稱直角三角形接地面的面積使天線阻抗頻寬大幅增加。在S_(11)<-10dB的情況下,實測的阻抗頻寬是從701MHz至7.1 GHz,阻抗頻寬百分比為164%,最大天線增益是 1.28 dBi,輻射場型趨近於全向性。可涵蓋GSM、GPS(1.575GHz)、DCS、PCS、UMTS、Bluetooth、LTE(700 MHz、2.3GHz、2.6GHz)、WiMAX及WLAN (2.4/5.2/5.8GHz)等無線通訊系統。 |
| 英文摘要 | A novel coplanar waveguide(CPW) fed four rectangular ring multi-function microstrip antenna is designed. The proposed antenna consists of four square ring radiation patch,dual symmetrical triangle shape ground plane and a tapered CPW-fed microstrip line. The four rectangular ring radiation patch can generate multiband frequencies and by adjusting the gap between dual symmetrical triangle shape ground plane and CPW-fed microstrip line, modifying the area of dual symmetrical triangle shape ground plane with the width of the CPW-fed microstrip line can increase the bandwidth. The measured return loss S_(11)<-10dB of the proposed antenna is 701MHz-7.1GHz, the impedance bandwidth is 164% and the peak gain of antenna is 1.28dBi. The proposed antenna has good radiation patterns and the operation frequency band can cover GSM, GPS(1.575GHz), DCS, PCS, UMTS, Bluetooth, LTE(700MHz, 2.3GHz, 2.6GHz), WiMAX and WLAN(2.4/5.2/5.8GHz) wireless communication systems. |
