| 中文摘要 | 本文中設計一款新型多頻段倒鉤形微帶天線,它能在無線通訊系統10個頻段中操作。其架構是由倒鉤形輻射貼片、雙對稱直角三角形接地面及共面波導饋入漸變形微帶線所組合。此天線的多頻段操作可經由適當的調整共面波導微帶線寬度、雙對稱直角三角形接地面之大小、倒鉤形輻射貼片形狀及其崁入的槽孔形狀。實作天線的尺寸是40×30×0.8mm3,經由實測後,得知在反射損失S11<-10dB 的情況下,其阻抗頻寬是171%(875MHz-11.31GHz),其操作頻段可涵蓋GSM(880MHz-960MHz)、GPS、DCS、PCS、UMTS、Bluetooth、LTE、WiMAX(3.5GHz)、WLAN及UWB等無線通訊系統,最大增益是1.03dBi。實測值與模擬結果相當一致,參數變化對頻寬及輻射場型的影響在本文中都詳加討論。 |
| 英文摘要 | A novel multiband barb-shaped microstrip antenna covering ten frequency bands are proposed for personal wireless communications terminals. The antenna is constructed from a barb-shaped radiation patch, dual symmetrical right-angled triangle shaped ground plane and a tapered CPW-fed microstrip line. The multiband operation will be achieved by using the width of the tapered CPW-fed microstrip line, the area of the right-angled triangle shaped ground plane and the size of the barb-shaped radiation patch with the embedded slot. The fabricated antenna have an overall dimension 40×30×0.8mm^3, and the measured results show that the antenna offers an impedance bandwidth over 171% (cover 875MHz-11.31GHz), at a reflection coefficient S11 <-10dB, it can be used to serve the GSM(880MHz-960MHz)、GPS、DCS、PCS、UMTS、Bluetooth、LTE、WiMAX、WLAN and UWB wireless communication systems and hasa maximum antenna gain of 1.03 dBi. The measured results agree well with the simulated ones. Important geometrical parameters determining the multiband performances of the antenna are explained in the paper. |
