Metasurface-driven Improvement in MIMO Antenna Performance by Addressing Mutual Coupling

Safia Jaouad, Chaymae Chahboun, Mohammed Ali Ennasar, Otman El Mrabet et autres

In this paper, a metasurface is proposed as an effective solution to enhance the performance of MIMO antennas by reducing mutual coupling. This reduction is attributed to the metasurface's negative permeability at the resonant frequency, which helps to block waves propagating between …
