Three Ways to Decouple Multiple Antennas in A Mobile Terminal

This paper introduces three antenna decoupling methods named MIMO multi-feed antenna, Single parasitic dual frequency antenna and Meta-Surface Antenna Array Decoupling (MAAD). They are respectively an eight MIMO multi-feed antenna system, which operating in the 5G wireless and sub 6 GHZ. Single parasitic dual frequency antenna, introduce a dual-frequency parasitic antenna element between the two antennas. Meta-surface antenna array, place a suspended meta-surface composed periodic square split ring resonators (SRRs) on the antenna array. These methods can significantly application scenarios in both mobile terminals and MIMO base stations of 5G wireless communication systems.
