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 1×2 MIMO antenna that has a short edge-to-edge distance (0.037λ0) 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.

A compact planar multiple-input multiple-output (MIMO) antenna array for 5G band is proposed in this paper. To improve the isolation of compact microstrip antenna array, this paper mainly presents an electromagnetic resonant ring method for MIMO antenna array. The proposed antenna can cover both the 3.3-3.6 GHz and 4.8-5 GHz bands proposed for the 5G band. The antenna proposed in this paper consists of two symmetrical meandered monopole radiators, grid structures, and a Y-shape element. Two different sizes of split-ring resonators (SRRs) are used to suppress the interference of the coupled signal to the antenna system; thereby it can reduce the mutual coupling effect. The experimental results show that the mutual coupling between the two elements is below -25 dB in both of the bands after adding the SRRs. And this antenna is only 23×19 mm2. Its compact size and structure can be used as a mobile terminal antenna.

Microstrip Patch

A compact triband microstrip patch MIMO antenna is proposed for WLAN applications. The antenna consists of two patches antenna elements, which are orthogonally placed to each other for high isolation at 2.4, 2.8 and 5.8 GHz frequency bands. On its ground plane, a Complementary Split Ring Resonators (CSRRs) is etched for size reduction and multiband generation. The proposed compact MIMO antenna covers an entire size of 58 x 45 x 1.6 mm3, with the patch size of 13.3 x 17.1 mm2. A 79% size reduction at 2.45 GHz was achieved for miniaturization, with a very low mutual coupling (S21 and S12) of -32 dB at all bands.
