Abstract

In this paper, we present a configuration of a wideband MIMO antenna array for 5G terminals. The single-element antenna has compact size, dual polarization, wide operating bandwidth covering the 5G N78 frequency band, and high isolation between the two input ports (>40 dB). The 4×1 radiation sub-array has dual polarization, low mutuality and high spatial diversity characteristics over the entire operating frequency range. The large-scale MIMO antenna array with a single 4×8 configuration can provide 8 independent beams azimuth sweep and 8 independent beams sweep azimuth. When exciting all ports in either horizontal or vertical bias, a large-scale MIMO antenna array can produce a main beam with a maximum realized gain of about 22 dBi. With many advantages of low profile, wideband, low mutuality, this large-scale MIMO antenna array can be applied to the current generation of 5G mobile base stations.
