A new metamaterial-based UWB MIMO antenna

In this paper, the design of an ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna based on metamaterial is proposed. The antenna is designed to achieve dual band-notched and high isolation using metamaterials. The traditional split ring resonators (SRRs) are used to achieve the band-notched effect and a new type of SRR is used to reduce the mutual coupling at both 3.1 GHz and 10 GHz. The antenna performance is presented through its S-parameters and radiation pattern. It shows the potential application in mobile devices or other small-scaled equipments.
