[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.
