本論文研究方向為多頻帶天線,應用於智慧型行動電話裝置上,以單極天線(monopole)附加寄生元件為主要天線設計架構,本論文天線設計可涵蓋頻帶為, LTE (Long Term Evolution) 700MHZ/ 900MHZ/ 1800MHZ/ 2300MHZ/ 2500MHZ(698~787, 900, 1800, 2300~2400, 2500~2690),全球移動通訊系統GSM (Global System for Mobile Communication, 880~960MHZ ),數位通訊系統DCS (Digital Communication System, 1710~1880MHZ),個人通訊系統PCS (Personal Communication System, 1850~1990MHZ),3G通用移動通訊系統UMTS (Universal Mobile Telecommunication System, 1920~2170MHZ),藍芽 (Bluetooth, 2400~2483.5MHZ),WLAN (Wireless Local Area Network, 2400~2488MHZ)等多個頻段。天線饋入方式為一個單極天線與上方寄生元件進行耦合饋入,再以背面接地面挖孔達到LTE700低頻之設計需求,天線尺寸為38mm*20mm,可應用於智慧型行動電話裝置。 This study direction focuses on multi-band antenna used for mobile phone. The main structure of the antenna is planar monopole antenna with parasitic elements。Proposed design antenna is operating at LTE 700/900/1800/2300/2500 (698~787 , 900 ,1800 , 2300 ~ 2400, 2500 ~ 2690 MHz), GSM 850/900 (824 ~ 960 MHz), DCS 1800 (17100 ~ 1880 MHz), PCS 1900 (1850 ~ 1990 MHz), UMTS 2100 (1920 ~ 2170 MHz), WLAN 2400 (2400 ~ 2480MHz) and Bluetooth (2400~2483.5MHz)。The planar monopole antenna coupled with parasitic elements excites two fundamental modes. By adjusting the parameters of the planar monopole and the ground plane, the antenna can operate multi-band frequency .This antenna can be used for LTE/WLAN/GSM applications. The overall dimension of antenna is within 50×120×0.8 mm3 area, with antenna area of 37×19 mm2 and planar structure。 |
