摘　　要：随着移动通信的快速发展,手机已成为不可或缺的通信工具,用户对手机的功能需求越来越高。如何设计一种小型化、低剖面和多频段的内置天线成为手机发展的难点和瓶颈。这里在研究倒F型天线的基础上,通过加载开槽缝隙技术实现了双分支结构,利用两条电流支路激发各自频段的方式,实现了一种工作于WCDMA和ISM频段的一款新颖的内置天线。通过仿真和实际测试结果说明该天线辐射性能良好,满足移动终端的应用要求。With the development of mobile communication, the cellphone becomes an indispensable communication tool, while the users has an increasingly high demand on functions of the cellphone. How to design a miniaturized, low-profile and multi-band antenna is now the difficult point and bottleneck of the cellphone development. Based on study of IFA antenna, a novel built-in antenna is proposed and designed, and it works in frequency bands of WCDMA and ISM. This twin-branch antenna uses two routes of electric current to drive their respective working frequency bands. Simulation and test indicate that this antenna has good performance and is very suitable for mobile communication terminals.
