| 中文摘要 | 本文設計一款新型多頻段三矩形環單極天線,天線架構是由三矩形環輻射貼片、雙對稱L形接地面及一條50Ω共面波導饋入微帶線所組成。此天線的三矩形環輻射貼片可產生多頻段之頻率,調整雙對稱L形接地面與微帶線之間距及改變雙對稱L形接地面的高度與三個矩形環輻射貼片之間的距離可增加阻抗頻寬。在反射損失S11 < -10dB的情況下,量測到的阻抗頻寬為1.9GHz-9.15GHz,頻寬比為131%,天線最大增益為1.17 dBi,並且有良好的輻射場型及操作頻段。可涵蓋UMTS、Bluetooth、LTE2300/2500、WLAN 2.4/5.2/5.8GHz及WiMAX等多個無線通訊系統。 |
| 英文摘要 | A novel multiband triple rectangular ring monopole antenna is presented. The proposed antenna consists of the triple rectangular ring radiation patch, dual symmetrical L shape ground plane and a 50Ω CPW-fed microstrip line. The triple rectangular ring radiation patch can generate multiband frequencies, by adjusting the gap between dual symmetrical L shape ground plane and microstrip line can increase the bandwidth at lower frequency band and modifying the height of dual symmetrical L shape ground plane with the distance between triple rectangular ring radiation patch can increase the bandwidth at upper frequency band. The measured return loss S11< -10dB of the proposed antenna is 1.9GHz-9.15GHz, the bandwidth of 131% and the peak gain of antenna about 1.17dBi. The proposed antenna has good radiation patterns and the operation frequency and can cover UMTS, Bluetooth, LTE2300/2500, WLAN 2.4/5.2/5.8GHz and WiMAX wireless communication systems. |
