摘要
为了满足移动终端设备天线小型化的要求,设计了一种应用于GSM900M/DCS1800M手机通信的小型化双频平面倒F天线。采用将辐射贴片折叠于介质基片上下两层并加载开槽线的方法,达到减小天线尺寸的效果,实际天线尺寸达到30mm×10mm×6mm,满足了手机内置天线大小的要求。采用HFSS9．2软件对天线进行了参数优化与特性分析,并且制作了实物模型,实物测试结果与仿真结果吻合良好。
This paper presents a type of compact dual - frequency antenna used in GSM800M ／ DCS1800M to meet the requirement of antenna miniaturization in mobile telecommunication. The size of the antenna is reduced to 30 mm ×10 mm ×6 mm with slots loaded and the patch folded. The antenna is analyzed and parameter -optimized using HFSS9. 2. A model is built and the testing results agree very well with the simulation results.
