Abstract

Objectives: To design A high isolation eight-element multiple and input multiple output (MIMO) antenna array tightly arranged based on embedded meta-material cells for the applications of 5G mobile terminals. Methods: In this, antenna array with a four block structure in which every block is formed by a method of tightly arranging two Inverted-F Antennas (IFAs) is used. These IFAs antennas are designed by the novel MIMO meta-material Cells which composed of two layers that are mutually connected through shorted pins are embedded with the high isolation using the High frequency structured simulator (HFSS) in the FR-4 (glass-reinforced epoxy laminate material) substrate. Findings: Simulation results reveal that the proposed IFAs antennas can provide isolation with a mutual coupling reduction of 18 dB with respect to the transmission coefficients and can also obtain sufficient bandwidth by the proposed antenna array for the 5G mobile terminals applications. Novelty: Isolation of Ports in every block can be improved by using the inductor.

Keywords: Multiple Input Multiple Outputs (MIMO); Meta-material cells; tightly-arranged pair and Inverted-F Antennas (IFAs)
