چکیده
With the development of 5G, Internet Things, and smart home technologies, miniaturized compact multi-antenna systems multiple-input multiple-output (MIMO) antenna arrays have attracted increasing attention. Reducing coupling between elements is essential to improving performance such MIMO system. In this work, we proposed a graphene-assembled, as an alternative material rather than metal, film-based array with high isolation for 5G application. The element improved by graphene assembly film (GAF) frequency selective surface strip. It shown that GAF operated at 3.5 GHz has realized gain 2.87 dBi. addition decoupling structure improves more 10 dB corrects radiation pattern operating frequency. interval 0.4λ above 25 dB. All experimental results show are efficient devices mobile communication.
