High Performance MIMO Array Antenna for 5G Systems
INTERNATIONAL JOURNAL OF MICROWAVE AND OPTICAL TECHNOLOGY, 2023
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. All these features make the antenna suitable for various 5G applications.
Isolation Techniques in MIMO Antennas for 5G Mobile Devices (Comprehensive Review
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.
