【摘要】：2013年年底,基于核心技术-LTE (LONG TERM EVOLUTION)的第四代移动通信牌照的发放,意味着我国移动通信行业进入了4G时代,对手机来说又增加了一个频段,如何在不增加复杂度的前提下天线实现多频段覆盖成为了业界关注的焦点之一。另一方面,随着国内加工工艺的发展,为增加手机外壳的强度、美化手机,各大手机厂商竞相推出了金属边框手机。但由于金属边框对手机天线电磁场辐射有很大影响,金属框会使手机天线的频带变窄、效率降低。因此,要在金属框手机上实现LTE全频段,是一大挑战。本文在金属边框手机天线调试过程中,深入分析优化,引入调谐技术,实现金属边框手机LTE天线技术。 论文首先介绍了金属边框手机以及LTE技术的发展,并分析了国内外金属边框手机LTE天线技术的情况,简要介绍了论文的内容。 然后介绍了手机天线的原理以及相应的无源参数和有源参数,如S参数,驻波,效率,带宽等,全向辐射效率(TRP),全向接收灵敏度(TIS)以及电磁波吸收比率(SAR),讨论了手机天线的几种形式以及天线的测试系统。接着通过制作模拟板对金属边框手机LTE天线进行初步调试,挑选出一种比较好的方案。并且采用HFSS15仿真软件进行仿真,优化分析天线的无源S参数性能,将实物调试数据与HFSS仿真数据做对比。 最后采用激光直接成型(LDS-LASER DIRECT STRUCTURING)工艺加工成成品天线组件,并对该金属边框手机进行有源数据测试。测试结果表明：本文设计天线的有源性能在GSM、CDMA、WCDMA、TD-SCDMA、LTE五个模式共18个频段均达到中移动入库指标。
[Abstract]:At the end of 2013, the issuance of the fourth generation mobile communication license based on LTE (LONG TERM EVOLUTION), the core technology, means that the mobile communication industry in our country has entered the 4G era, which has added a frequency band to the mobile phone. How to achieve multi-band coverage without increasing complexity has become one of the focuses in the industry. On the other hand, with the development of domestic processing technology, in order to increase the strength of mobile phone shell and beautify the mobile phone, the major mobile phone manufacturers have launched metal border mobile phone. However, metal border has great influence on electromagnetic radiation of mobile phone antenna. Metal frame will narrow the frequency band and reduce the efficiency of mobile phone antenna. Therefore, it is a challenge to achieve full-frequency LTE on metal-framed mobile phones. In this paper, during the debugging process of metal border mobile phone antenna, the optimization is deeply analyzed, and the tuning technology is introduced to realize the metal border mobile phone LTE antenna technology. Firstly, this paper introduces the development of metal border mobile phone and LTE technology, analyzes the LTE antenna technology of metal border mobile phone at home and abroad, and briefly introduces the content of the paper. Then the principle of mobile phone antenna and the corresponding passive and active parameters, such as S parameter, standing wave, efficiency, bandwidth, omnidirectional radiation efficiency (TRP), omnidirectional receiver sensitivity (TIS) and electromagnetic wave absorption ratio (SAR), are introduced. Several forms of mobile phone antenna and the antenna testing system are discussed. Then the LTE antenna of metal border mobile phone is preliminarily debugged by making analogue board, and a better scheme is selected. The HFSS15 simulation software is used to optimize and analyze the passive S-parameter performance of the antenna. The physical debugging data is compared with the HFSS simulation data. Finally, laser direct molding (LDS-LASER DIRECT STRUCTURING) process was used to fabricate the finished antenna module, and the active data of the metal border cell phone was tested. The test results show that the active performance of the antenna designed in this paper can reach the mid-moving storage target in 18 frequency bands of five modes of GSM,CDMA,WCDMA,TD-SCDMA,LTE.
