“…However, neutralization-line [9,10] has been used to improve the isolation between two-monopole-antenna system. There are still other methods to achieve a better isolation by using metalized via wall [11], electromagnetic band-gap (EBG) structure [12][13][14], etching slots in the ground plane [15,16], and ELC resonator [17].…”

In this article, a parasitic element structure is proposed to reduce the mutual coupling in a miniaturized microstrip dual-band Multiple-Input Multiple-Output (MIMO) antenna, which resonates at (7.8 GHz) for X-band and at (14.2 GHz) for Ku band applications. The design of the primary antenna consists of two identical radiators placed on a 24 × 20 mm 2 Fr-4 substrate, which are excited by orthogonal microstrip feed lines. In addition, a single complementary split ring resonator (S-CSRR) is used to improve the performance of proposed antenna. Simulation and measurement were used to study the antenna performance, including reflection coefficients, coupling between the two input ports, radiation efficiency, and the radiation pattern. The measured results show that the proposed antenna achieves two operating bands with impedance bandwidths (|S 11 | ≤ −10 dB) of 560 MHz (7.6 to 8.16 GHz) and 600 MHz (13.8 to 14.4 GHz) and mutual coupling (|S 12 | < −26 dB), which are suitable for X/Ku band applications.

“…In [4][5][6][7][8][9], the mutual coupling between ports can be reduced by using defected ground structures (DGS) at the ground plane. In other words, the utilization of electromagnetic band gap (EBG) structure has the ability to enhance the isolation as well as increase the MIMO antenna performance [10][11][12]. The work in [13] presents a MIMO antenna with improved isolation using meta-material structure.…”

In this paper, a compact planar mono-band multiple input multiple output (MIMO) antenna with four monopole elements is presented for X-band satellite applications (7.2-7.8 GHz). The MIMO antenna resonates at 7.5 GHz, with high isolation (more than 26 dB) between its ports. It consists of a four closely arranged symmetric monopole antennas with edge-to-edge distance of 7.2 mm (0.18λ). In the top face, different forms are loaded at the rectangular patch. A U-shaped slot defected ground structure (DGS) has embedded in the ground plane. The prototype of the proposed MIMO antenna is simulated, fabricated, and measured to examine the performance of this antenna in terms of S parameters, radiation patterns, envelope of correlation coefficient (ECC), and diversity gain (DG). As a result, the presented antenna has a high isolation (S 12 < −26 dB) at 7.5 GHz with an impedance bandwidth of 430 MHz (7.28 GHz-7.71 GHz), which covers the X-band applications. The diversity gain is about 10, and the envelope correlation coefficient of antenna is less than 0.02 which means that the antenna has high performance at the resonance frequency.

“…Many solutions have been proposed to reduce mutual coupling between antenna elements using, e.g., shorting pins [4], compact coplanar waveguide (CPW) feeding [5], electromagnetic band gap (EBG) [6], parallel coupled-line resonators [7]. These methods have reached a recognizable improvement in isolation enhancement.…”

In this paper, a multiple-input multipleoutput (MIMO) antenna with high isolation is designed using defected ground structure (DGS). The proposed antenna is constructed by two sets of four elements (2×2), which are designed at the central frequency of 3.5 GHz for Worldwide Interoperability for Microwave Access (WiMAX) applications. The antenna is fabricated on a FR4 substrate with an overall size of 144 × 99 × 1.6 mm. Thanks to DGS, the designed MIMO antenna achieves a high isolation of 30 dB and a high radiation efficiency of over 90%. Besides, this MIMO antenna attains a 7.5 dBi gain. There is a good agreement between the simulated S-parameters and the measurement results.
