摘　　要：大规模3D MIMO半波天线的小型化研究一直是一个热门课题,尤其在5G时代。通过天线基础理论和FDTD仿真,证明在阵列阵元间填充介质和缩小阵元间距后,同样可以获得理想的波束赋形效果。同时还研究了阵元间距与填充介质参数的关系,提出了2种在阵元间填充介质的方式方法,证明了大规模3D MIMO半波天线小型化的可行性和实用性,具有一定的研发和推广价值。Miniaturization of large scale 3D MIMO half wave antenna has always been a hot topic,especially in 5G era. Based on the antenna basic theory and FDTD simulation,it is proved that the ideal beamforming effect can be obtained after the array elements are filled with dielectric and the spacing of the array elements is reduced. At the same time,the relationship between the array element spacing and dielectric parameters are also studied,two methods of filling dielectric in arrays are proposed,and it proves the feasibility and practicality of large-scale 3D MIMO half wave antenna,and it has certain research and development and promotion value.
