摘要
本文提出一种新型平面倒置F型三频手机天线(PIFA)。天线采取单馈点同轴馈电,上层辐射片开h形槽孔,应用时域有限差分法对天线进行设计和仿真,在GSM900MHz,DCS1800MHz和ISM2450MHz 3个频段的增益分别达到了0.1dBi,0.25dBi和0.4dBi,带宽分别达到了6.44%,6.67%和4.5%,表明该天线可在三个频段工作,满足了新一代无线通信系统对频段、带宽和增益的要求。
A new tri - band P1FA is presented. Take point of a single feed antenna coaxial feed, the upper radiation film with a ＂h＂ groove ,applies FDTD to design and simulation, the plus partly reaches 0. IdBi,0.25dBi and 0.4dBi and the bandwidth partly reaches 6.44% ,6.67% and 4.5% at GSMg00MHz,DCS1800MHz and ISM2450MHz ,the results indicate that the antenna can work at 3 frequency bands , meet a new generation of wireless communication system frequency and bandwidth requirements.
