中文摘要 | 本文中設計一款小型橢圓極化平面倒F 型衞星天線,此天線以橢圓極化波達 到衛星通訊之功能。射頻訊號經饋電體及導桿間接傳導饋入RF 接頭及反射體。在 S11<-10dB 時的阻抗頻寛是23.6%,頻率是從 1.46 GHz 至1.85 GHz,天缐増益高 達13 dBi。此天線重量輕且體積小,亦能使用於陸地上L 頻段通訊,可增進系統 增益、改善系統靈敏度。微型化改變以往碟形天線反射體,同時攜帶方便、安裝 容易且外罩抗風性良好,十分符合適於載具的機動化,更適合於地理條件艱困區 域使用。 |
英文摘要 | In this paper, a compact elliptical polarization planar inverted F(PIFA) satellite antenna is designed, which can achieved the satellite communication with elliptical polarization. RF signal is transmitted through the feed and RF connector with reflector indirectly. The prototype are fabricated and measured. The input impedance bandwidth is 20.3% for S11<-10dB, and frequency is from 1.450 GHz to 1.790 GHz. The antenna peak gain is 13dBi. This compact antenna also can be work on L-band terrestrial communication and easy to carry、install and replace dish reflector(mesh or solid). Technical developments and advantage function will help connectivity under all kind ofsevere weather & environment condition. |
