The impact of several subwavelength metamaterial particles based on split-ring inspired resonators to enhance the decoupling level in a two planar inverted-F antenna multi-input multi-output printed circuit board system is investigated. The Sparameters, antenna performance, electric and magnetic field distribution are simulated and analyzed by means of the full 3D electromagnetic simulator CST Microwave Studio at 2.45 GHz. The obtained results show a notable coupling reduction level in the three analyzed cases and a trade-off between isolation/antenna performance/area.
