【摘要】：随着移动通信技术的飞速发展,市场对手机终端提出了越来越高的要求。手机天线作为手机的重要部件之一,其性能直接影响着手机的整体性能和外型设计。手机天线的小型化、多频带、宽带化设计是当前天线设计的热点和难点。本文就是针对手机天线研究的热点和发展趋势,在对手机天线小型化、多频带设计做了重点阐述的基础上,以当前主流手机内置天线PIFA天线为基础,采用曲流和折叠等技术设计出了几种小型化、多频带工作的手机内置天线。 本文介绍了各类手机天线。 PIFA天线以其体积小、易于组阵、易于制作和低的SAR值等优点成为当前手机内置天线中使用最为广泛的天线。因此,它也是本文介绍的重点内容。本文借助仿真软件HFSS,经过反复调整和多次优化,最终设计出了三款小型化和多频带工作的PIFA手机天线,包括两款双频带、一款三频带(GSM/DCS/ISM) PIFA手机天线。在对手机天线小型化和多频带设计的几种方法分析比较之后,采用双L型槽实现双频带(GSM/DCS)的小型化设计；采用U型槽和折叠相结合的方法实现双频带(GSM/ISM)的设计；采用双U型槽和折叠技术相结合的方法实现三频带(GSM/DCS/ISM)的设计。与其他的设计方法相比,以上方法具有设计简单、易于实现等优点,也是手机内置天线设计中采用较多的方法。通过仿真和优化,三款天线基本满足了手机天线的性能要求,有着很好的应用前景。 最后本文对所做工作进行了总结和展望,并提出了论文存在不足和有待改善的地方。
[Abstract]:With the rapid development of mobile communication technology, the market has put forward higher and higher requirements for mobile terminals. As one of the important components of mobile phone, the performance of antenna has a direct impact on the overall performance and appearance design of mobile phone. The miniaturization, multi-band and wideband design of mobile antenna is a hot and difficult point in antenna design. This paper is aimed at the hot spot and development trend of mobile phone antenna research, on the basis of focusing on the miniaturization and multi-band design of mobile phone antenna, based on the current mainstream mobile phone built-in antenna PIFA antenna. Several miniaturized and multi-band mobile phone built-in antennas are designed by using meandering and folding techniques. This paper introduces various kinds of mobile phone antennas. PIFA antenna has become the most widely used antenna in mobile phone because of its small size, easy array, easy fabrication and low SAR value. Therefore, it is also the focus of this article. With the aid of the simulation software HFSS, after repeated adjustment and multiple optimization, three miniaturized and multi-band PIFA mobile phone antennas are designed, including two dual-band antennas and one three-band (GSM/DCS/ISM) PIFA mobile phone antenna. After the analysis and comparison of several methods of antenna miniaturization and multi-band design, the miniaturization design of dual-band (GSM/DCS) is realized by using double-L slot, and the design of dual-band (GSM/ISM) is realized by combining U-groove and folding. The design of three frequency band (GSM/DCS/ISM) is realized by the combination of double U groove and folding technique. Compared with other design methods, these methods have the advantages of simple design and easy implementation. Through simulation and optimization, the three antennas basically meet the performance requirements of the mobile phone antenna, and have a good application prospect. Finally, this paper summarizes and prospects the work done, and points out the deficiency and the need to be improved.
