“…The primary advantage of this approach is its ability to improve antenna isolation based on the intrinsic characteristics of the antenna itself, eliminating the need for additional decoupling networks. Several representative works have been presented [19], [20], [21], [22], [23], [24], [25]. In [19], the mutual coupling is mitigated by adjusting the feeding position.…”

This paper presents a multi-element multiple-input multiple-output (MIMO) antenna with self-isolation and flexible characteristics. The primary radiators of the proposed antenna consist of multiple ellipse-shaped patches arranged in an H-plane configuration. Self-decoupling is achieved by simultaneously different operating modes on the excited element (TM 10 mode) and non-excited element (TM 02 mode). The proposed method also shows strong extensibility. The measurements on the fabricated 4-element MIMO antenna demonstrate that the proposed decoupling method can improve the isolation by 14 dB. The antenna shows good MIMO diversity performances with respect to the envelope correlation coefficient and diversity gain. Additionally, the antenna also works effectively in when the substrate is bent, which contributes to significantly increasing the applicability of the proposed method in comparison with the other reported methods.

“…Another method is to use a special ground design with slots [20]. In [21], [22], the patch is cut with various shapes of slots. In [23], the self-decoupling technique is based on the weak field on the patch.…”

“…The 8×8 MIMO method is also more efficient than 68% [13]. Self-isolating mm-wave 1×2 MIMO antenna with a gain of 9.6 dB, extreme isolation of 51 dB, efficiency above 90%, and ECC smaller than 0.005 for a given frequency of 28-37.5 GHz [14].

This research work describes a compact four-port multiple input multiple output (MIMO) antenna using defective ground structure (DGS), and it perfectly supports the n77, n78, and n79 frequencies in 5G new radios (NR) bands. It can cover a wideband from 3.4 to 5.4 GHz with good impedance matching. The pair of antenna elements are orientated opposite to another pair with DGS. Due to this technique, it has minimal complexity, is less expensive, and improves isolation. It has also improved the frequency band's reflection coefficient and range using MIMO antenna with different stub lengths. Because it is less expensive, FR-4 substrate is used in the implementation of all antennas. Each antenna element has two identical stubs linked to the primary radiator. On the primary radiating element, a ''HI'' slot is created. The partial ground enhances impedance matching and radiation properties throughout the targeted band. <span>The total dimensions of the four-port MIMO antenna are 46×30×1.6 mm<sup>3</sup>. The array elements' mutual coupling in the simulation is -14 dB. The ECC value is below 0.01, and the diversity gain (DG) is less than 10 dB. The suggested designs' measured gain ranges from 10 to 11.0 dB, and the radiation efficiency is nearly 91%.</span>

“…Recently, several low coupling design techniques have been proposed to reduce the mutual coupling of adjacent antennas. The details are as follows: defective ground structure (DGS) [ 14 ], parasitic element [ 15 ], electromagnetic band gap (EBG) [ 16 ], neutralization line [ 17 ] and decoupling network [ 18 ] methods. Some of these methods require the antenna spatial distance, and others degrade the radiation of MIMO antennas or require complex construction MIMO antenna designs.…”

This paper presents an MIMO antenna for vehicle-to-everything (V2X) communication, which adopts two ways of combline filters and absorption wall decoupling. A combline filter and an absorption wall are used, respectively, for internal and external decoupling. The combline filter is incorporated between the ground of the two adjacent antennas, which reduces the mutual coupling between them. Additionally, the mutual coupling of radiation between adjacent antennas is significantly reduced by the absorber wall. These combline filters and absorber walls use the method of electromagnetic field distribution to explain the reduction in the mutual coupling between the adjacent antennas. The transmission coefficient and surface current distribution explain the effectiveness of the decoupling structure. When the frequency is between 3.8 and 4.8 GHz, the simulation and measurement results show that S11 is less than −10 dB, the bandwidth is 25% and the peak gain is 7.8 dBi. In addition, the proposed MIMO antenna has a high isolation between antenna units (>37 dB), and the envelop correlation coefficient (ECC) is less than 0.005.
