“…In order to study the scattering properties (reflection coefficient S 11 , and transmission coefficient S 21 ), a quasi-transverse electromagnetic (TEM) waveguide setup was implemented in the commercially available EM solver HFSS 14 [13,14] as depicted in Figure 1. Appropriate perfect electric conductor (PEC) and perfect magnetic conductor (PMC) boundaries were imposed in the z and x directions, respectively, to propagate the dominant TEM plane wave along y direction, with the electric field polarized perpendicular to, and the magnetic field parallel to, the periodical WG-MTMs.…”

Abstract-In this paper, suppression of mutual coupling is achieved using compact waveguided metamaterials (WG-MTMs) in between elements of a densely packed microstrip array. Both the E-plane internally folded complementary split ring resonator and the H-plane internally folded complementary split ring resonator are employed to reduce the mutual coupling between adjacent elements. Coupling suppression of 18 dB and 9 dB, for elements in the E-plane and H-plane, respectively, is demonstrated. Due to the compact size of the waveguided metamaterials, the edge-to-edge separation between elements is kept at only 0.093λ 0 . With the same element spacing, a 2 × 2 array is also simulated with compact WG-MTMs. The proposed structure reduces the array size and enables the implementation of compact Multiple-Input-Multiple-Output systems.

“…Metamaterials [1,7], different shapes of resonator [2,6,8,9] and EBG structure [3][4][5]10] are the mostly used methods to reduce mutual coupling effectively. Some structures have used defective ground structure (DGS) [6], but it increases back radiation which is undesired.…”

Abstract-This paper presents designs of novel E-plane spiro meander line uniplanar compact electromagnetic bandgap (E-SMLUC-EBG) and H-plane spiro meander line uniplanar compact electromagnetic bandgap (H-SMLUC-EBG) structures. The proposed EBG has been applied in mutual coupling reduction of a dual-element multiple input multiple output (MIMO) antenna system for WLAN by placing an EBG structure between the radiating antennas. Compact size of EBG helps in reducing the edge to edge distance between antennas which is 0.14λ 0 in this case, and it increases the compactness of integrated circuit. It gives 19 dB and 11 dB simulated mutual coupling reduction in E-plane and Hplane respectively at 5.8 GHz. Measured isolation improvement of 20.3 dB for E-plane and 14.7 dB for H-plane has been achieved. This coupling reduction is also confirmed by surface current and correlation coefficient plots. The four-element (2 × 2) MIMO antenna system with proposed EBG is also simulated.

Abstract-Nowadays everyone needs electronic gadgets in compact size, and single device should accomplish all the tasks. A compact MIMO antenna resonating at multi-band of frequencies is proposed in the current research work. The proposed MIMO antenna consists of two elements. The edge to edge separation between the two antennas is λ 0 /31 and still maintains low mutual coupling levels between the two antennas.
