摘要：
In this paper, a metamaterial-based novel antenna-mutual-coupling reduction structure is proposed and demonstrated. The structure consists of a three layer metamaterial frequency selective surface (MFSS) superstrate with split-ring resonators and metal grids. The MFSS means metamaterial frequency selective surface that has the metamaterial performance along the substrate and the frequency selective characteristic on the normal direction of the antenna array simultaneously. A 1x2 MIMO antenna that has a short edge-to-edge distance (0.037 lambda(0)) is designed as an illustration to demonstrate the validity of the meta-surface for mutual. When loaded with the proposed MFSS, the mutual coupling between the antenna elements is significantly reduced and the gain of the antenna array is improved by 2.5 dBi.
