【摘要】：随着人们对现代通信质量的要求逐步上升，随时随地跨地域的移动通信已经成为人们日常生活中必不可少的一个重要部分。移动通信经历了从有线到无线及从单纯语音到多媒体传输的前所未有的全新变革，现在已经成为发展速度最快、最活跃的领域之一。与此同时，因为移动通信能带给人们在工作和生活上的快捷和便利，使用移动通信的用户数也在迅猛增长，移动通信只有质量越来越好，容量越来越大才能满足日益增长的用户需求。目前人们对数据通信及多媒体业务需求不断增长，4G移动通信系统的建设越来越迫切，4G系统同时具备3G与WLAN的优点，能够传输与高清电视质量相近的视频图像，其最高下载及上传速度分别可达到100Mbps及20Mbps，几乎所有用户的无线服务都可满足。天线作为移动通信系统的接入设备，，质量及性能的好坏直接影响人们对一个通信系统的感知与体验，因此对基站天线及终端天线的研究具有重要意义。本文主要通过对目前移动通信的发展进行阐述，分析基站天线及移动终端天线的发展现状及存在的问题，结合4G移动通信系统基站天线和终端天线的最新趋势和发展方向。应用HFSS仿真软件设计并仿真一种可以用于LTE系统的终端MIMO天线，以期优化现有的MIMO天线设计方案，并提出优化方案的技术保障措施。
[Abstract]:With the increasing demand for the quality of modern communication, mobile communication has become an essential part of people's daily life. Mobile communication has experienced unprecedented changes from wired to wireless and from pure voice to multimedia transmission. Now it has become one of the fastest growing and most active fields. At the same time, because mobile communication can bring people quick and convenient in their work and life, the number of users using mobile communication is growing rapidly, and the quality of mobile communication is getting better and better. Capacity is increasing to meet the growing needs of users. At present, the demand for data communication and multimedia services is increasing. The construction of 4G mobile communication system is becoming more and more urgent. The 4G system has the advantages of 3G and WLAN at the same time, and it can transmit video images with the same quality as HDTV. Its maximum download and upload speeds can reach 100Mbps and 20 Mbpss respectively, almost all users of wireless services can be satisfied. As the access equipment of mobile communication system, the quality and performance of antenna directly affect the perception and experience of a communication system, so the research of base station antenna and terminal antenna is of great significance. In this paper, the development of mobile communication is described, the current situation and problems of base station antenna and mobile terminal antenna are analyzed, and the latest trend and development direction of base station antenna and terminal antenna are combined with 4G mobile communication system. A terminal MIMO antenna which can be used in LTE system is designed and simulated by using HFSS simulation software, in order to optimize the existing MIMO antenna design scheme, and put forward the technical safeguard measures of the optimization scheme.
