With the rising need for high-speed data rates, the fifth generation (5G) has emerged as the dominant technology within the telecommunications systems field. One of the most aspects of designing such high-capacity, low latency, and adaptable systems is antenna design. In this article, we presented a two-element MIMO (multi-input & multi-output) antenna that has good advantages in terms of its small size (19 × 23 × 1.6 mm^3) and operates in several wide frequency bands from 1 GHz to 18 GHz. Two models were created for this antenna design. The first was simulated using CST Studio, while the second was based on realistic manufacturing. As a result, the discussions on all parameters were selected for the performance diagnosis of the proposed antenna. We observed the antenna operating at four main resonance frequencies (4.5 GHz, 9 GHz, 13 GHz, and 17 GHz). So, the S-Parameter is <-10 dB at all frequencies from 1 GHz to 18 GHz. In addition, we noticed that the isolation ratio among the elements in a MIMO antenna composition reaches-70 dB when using Spatial and Separated Ground. Furthermore, this antenna has a gain between 3 dB and 9.8 dB and an overall efficiency between 70 % and 98 % for all frequency bands.

Radioelectronics and Communications Systems, 2023
Recently, due to the fast development in multimedia applications of wireless communication systems and demands of increasing the capacity and data rates to meet the requirements of 5G mobile communication systems, new transmission techniques are needed. One of the powerful enabling tools of the 5G communication systems is the multi-input multi-output (MIMO) antenna system employing multiple antennas and utilizing the multipath fading mobile environment to increase the channel capacity without any additional bandwidth and/or transmitted power. However, because of the limited space of mobile devices, the distances between antennas are decreasing. The mutual coupling between antennas severely affects the overall performance of the MIMO system. So, isolation improvement methods are applied to reduce these influences. In this review, different isolation techniques and their features and drawbacks are presented, and the techniques for applying them in modern MIMO antenna systems are illustrated. Besides, the performance characteristics of these MIMO systems are compared. The review also contains basic concepts of the MIMO antenna system and its performance metrics. Finally, the future directions and trends for the MIMO antenna system design are discussed briefly.

Computer Systems Science and Engineering, 2022
A compact self-isolated Multi Input Multi Output (MIMO) antenna array is presented for 5G mobile phone devices. The proposed antenna system is operating at the 3.5 GHz band (3400-3600 MHz) and consists of eight antenna elements placed along two side edges of a mobile device, which meets the current trend requirements of full-screen smartphone devices. Each antenna element is divided into two parts, a front part and back part. The front part consists of an I-shaped feeding line and a modified Hilbert fractal monopole antenna, whereas the back part is an L-shaped element shorted to the system ground by a 0.5 mm short stub. A desirable compactness can be obtained by utilizing the Hilbert space-filling property where the antenna element's overall planar size printed on the side-edge frame is just (9.57 mm × 5.99 mm). The proposed MIMO antenna system has been simulated, analyzed, fabricated and tested. Based on the selfisolated property, good isolation (better than 15 dB) is attained without employing additional decoupling elements and/or isolation techniques, which increases system complexity and reduces the antenna efficiency. The scattering parameters, antenna efficiencies, antenna gains, and antenna radiation characteristics are investigated to assess the proposed antenna performance. For evaluating the proposed antenna array system performance, the Envelope Correlation Coefficients (ECCs), Mean Effective Gains (MEGs) and channel capacity are calculated. Desirable antenna and MIMO performances are evaluated to confirm the suitability of the proposed MIMO antenna system for 5G mobile terminals.
