摘要
文章提出一种可应用于4G/5G工作频段且应用分集技术解耦的8×8频率可重构MIMO系统。八天线阵列中包括4个可切换于2.6 GHz频段和3.5 GHz频段的频率可重构天线模块以及4个应用于3.5 GHz频段的5G模块。由于频率可重构技术的应用,该系统可满足网络传输速率等多种要求,进一步提高终端设备的空间利用率和系统应用的灵活性。文章给出了MIMO系统切换前后的S参数和包络相关系数等参数的计算结果,结果显示出多天线阵列的可应用性。
This paper presents an 8×8 frequency reconfigurable MIMO system which can be applied to 4G/5G working frequency bands and decoupled by diversity technology.The eight antenna array consists of four frequency reconfigurable antenna modules which can be switched to 2.6 GHz frequency band and 3.5 GHz frequency band and four 5G modules which can be applied to 3.5 GHz frequency band.Because of the application of frequency reconfigurable technology,the system can meet the requirements of network transmission rate and other requirements,and further improve the space utilization of terminal equipment and the flexibility of system application.The calculation results of S parameters and envelope correlation coefficient before and after switching of MIMO system are given.The results show the availability of multi-antenna arrays.
