摘　　要：利用在单极子天线中开缝产生两条谐振路径,本文设计出一个地板表面分布电流小,性能稳定,频率高达2600 MHz时仍具有与对称阵子相似的辐射方向图,宽带宽（高低频带宽分别为877~960MHz,1680~3189MHz）,结构紧凑（宽为39mm,长为13mm）,地板尺寸小的平面手机天线.该天线结构简单,制作容易,适合应用在小型的手机中.天线的仿真结果和测试结果十分吻合.A broadband（the first band is 877~960 MHz,and the second band is 1680~3189 MHz） planar phone antenna with weak ground surface current and stable performances is proposed,which has two resonant paths by eroding a slot on a monopole antenna.The radiation patterns at 2600 MHz of the antenna are still similar to the ones of monopole,and the size of ground plane is compact.Moreover,the antenna has a simple construction with a compact-size of 39mm in width and 13mm in length,and it can be easily fabricated.Simulated and measured results of the design are in a good agreement,so the antenna can be equipped in the system of mini mobile phone.
