| 摘 要： | 提出了一种基于缺陷地结构(DGS-detected ground structure)的新型平面倒置F型三频手机天线(PIFA).该天线在辐射片下面的接地板上进行开槽,有效地减少了天线体积,使天线能够在44mm×25 mm×4 mm的体积上满足GSM-900/DCS-1800/UMTS-2000的带宽要求,在其频率范围内回波损耗可达到-5 dB以下,有效地展宽了传统倒F天线的工作带宽,实现了天线的小型化、宽频带的要求,在通信系统中有较好的通信前景.

| Abstract: | This paper presented a novel compact planar inverted F antenna based on the detected ground structure.The proposed antenna introduced the open-end slots in the ground plane under the radiating patch within the limits of a 44 mm×25 mm×4 mm volume which covered GSM-900 /DCS-1800/IUMTS-2000 bands at S11<-5dB.The traditional inverted F antenna bandwidth was effectively broadened.The proposed antenna was miniaturization,broadband and had great potential in practical application. |
