【摘要】：随着移动通信行业，移动设备的快速发展，移动终端向着更加小型和宽带多频化发展。现在通讯的常用频段包括GSM900/GSM1800/DCS/WIFI/Bluetooth/WLAN。同时LTE技术由于其高速的数据传输速率也将在第四代移动通讯系统中被大规模使用，越来越小的空间和更多工作模式给手机天线的设计带来更高要求。本文首先介绍了手机天线发展历程和手机天线研究现状，对手机天线的未来发展趋势进行预测。接着介绍了微带天线基本工作原理，辐射参量和测试工具。第三章介绍了常见的手机天线，通过具体实例介绍了手机天线的小型化和基于多频的方法。本文主要提出两种新型手机天线并进行详细分析。一种是覆盖八个频段的倒F天线（IFA Inverted-F Antenna），该天线由IFA天线增加寄生单元和谐振单元构成，通过空间折叠法有效减小天线体积。该天线体积比同类天线体积减小60%左右。另一个天线是宽带LTE单极子天线，该天线通过CRLH加载展宽天线带宽，同时将体积限制在较小范围内。该单极子天线可以工作在GSM/TD-SCDMA/TD-LTE/WLAN频段。最后，，对这两个天线进行加工测试，性能测试结果良好，具有较大应用潜力。
[Abstract]:With the rapid development of mobile communication industry and mobile devices, mobile terminals are becoming smaller and more broadband. The current frequency bands include GSM900 / GSM 1800% DCS / WIFI / Bluetooth / WLAN. At the same time, the LTE technology will be widely used in the fourth generation mobile communication system because of its high speed data transmission rate. The smaller and smaller space and more work mode make the design of mobile phone antenna more demanding. In this paper, the development history of mobile phone antenna and the research status of mobile phone antenna are introduced, and the future development trend of mobile phone antenna is forecasted. Then the basic working principle, radiation parameters and testing tools of microstrip antenna are introduced. In the third chapter, the common antenna of mobile phone is introduced, and the miniaturization of antenna and the method based on multi-frequency are introduced. In this paper, two new mobile phone antennas are proposed and analyzed in detail. One is the inverted F antenna (IFA verted-F Antenna), which is composed of extra parasitic elements and resonant elements, which can effectively reduce the size of the antenna by space folding. The volume of the antenna is about 60% smaller than that of the same antenna. The other antenna is the broadband LTE monopole antenna, which is loaded with CRLH to broaden the bandwidth of the antenna, while limiting the volume to a smaller range. The monopole antenna works in the GSM / TD-SCDMA / TD-LTE / WLAN band. Finally, the processing test of the two antennas shows that the performance test results are good and have great application potential.
