摘　　要：本文提出了一种适用于4G手机的平面天线,该天线采用接地板共面和多枝节连接地板结构扩展带宽,可以产生0.75GHz、2.6GHz和3.5GHz三个工作频率,增益分别为2.7d Bi、4.9d Bi和5.3d Bi,工作频带为0.69GHz^0.82GHz和2.49GHz^4.06GHz.仿真和测试结果基本吻合。研究表明该天线可以满足4G手机工作需求,具有较好的应用前景。A planar antenna tor 4G mobile phone is proposed. Cop/aner structure and branches connected to ground are uesd to extend bandwidth. The antenna has three resonant tYequcncies of 0.75GHz ,2.6GHz and 3.5GHz, whose gains are 2.7dBi,4.9dBi and 5.3dBi, respectively. The working band covers 0.69GHz^0.82GHz anti 2.49GHz-4.06GHz. The measured data show very good agreement with the simulation, The study indicates thai the proposed anlenna can satisfy the 4G mobile phone demand, with a good prospect of application.
