| 摘 要： | 为了满足现代多制式移动通信频段的需求,设计一种可覆盖大部分移动通信频段的超宽带天线。同时为了抑制与其他通信设备的干扰,在天线馈线旁加载两个U型谐振环用来获得双阻带特性。天线总尺寸为200mm×150 mm×3 mm。通过调整U型环可以获得不同的阻带特性。设计结果表明:天线工作在750~1150MHz和1650~2450MHz。该天线成本低、易集成,同时具有全向辐射特性,适用于现代移动通信需要。

| Abstract: | In order to meet the frequency band requirements of the modem multi-standard mobile communication,a UWB （ultra wide band） antenna covering the most mobile communication frequency bands has been proposed in this paper.Two U-shaped parasitic elements are designed on both sides of the feed line generating two band-notches,aiming to block the interference from other communication devices.The overall size of the proposed antenna is 200 mm150 mm3 mm.Different band-notch characteristic can be acquired by adjusting the U-shaped parasitic elements.The proposed antenna work frequency band is at 750-1150MHz and 1650-2450MHz.The antenna is suitable for the modem mobile communication applications for its low cost,easy integrated,operation frequency band and omni-directional radiation patterns. |
