Abstract

SummaryThis study presents the design, fabrication, and measurement of a novel MIMO antenna for 28 GHz 5G applications. The design includes two compact antennas with dimensions of 12.8 × 12.8 × 1.6 mm3, placed side by side in a symmetrical arrangement. The antenna being considered operates within the 28 GHz frequency range and has excellent characteristics in terms of reflection coefficient, isolation, and impedance matching. The measurements conducted encompassed both single and MIMO setups and focused on important parameters such the reflection coefficient, transmission coefficient, gain, and efficiency. The MIMO antenna exhibited a reflection coefficient of −62.52 dB at a frequency of 27.93 GHz, while the transmission coefficient was found to be −37.23 dB. The antenna attained a gain of 6.02 dB relative to an isotropic radiator (dBi) and exhibited a maximum efficiency of 90.73%, encompassing a bandwidth of 4.45 MHz (MHz). The simulated envelope correlation coefficient (ECC) was found to be less than 0.003, indicating a very low error rate. Additionally, the antenna attained a diversity gain of 9.998 dB. The suggested MIMO antenna is very suitable for 5G applications operating at 28 GHz.

用于 28 GHz 5G 应用的紧凑型 6 形高隔离度 MIMO 天线

摘要本研究介绍了用于 28 GHz 5G 应用的新型 MIMO 天线的设计、制造和测量。设计包括两个尺寸为 12.8 × 12.8 × 1.6 mm3 的紧凑型天线，以对称方式并排放置。所考虑的天线在 28 GHz 频率范围内工作，在反射系数、隔离度和阻抗匹配方面具有出色的特性。所进行的测量包括单个和多输入多输出（MIMO）设置，重点是反射系数、传输系数、增益和效率等重要参数。在频率为 27.93 GHz 时，MIMO 天线的反射系数为 -62.52 dB，传输系数为 -37.23 dB。相对于各向同性辐射器，天线的增益为 6.02 dBi，最大效率为 90.73%，带宽为 4.45 MHz。模拟包络相关系数 (ECC) 小于 0.003，表明误差率非常低。此外，该天线的分集增益达到了 9.998 dB。所建议的 MIMO 天线非常适合在 28 GHz 频率下运行的 5G 应用。

期刊介绍： The International Journal of Communication Systems provides a forum for R&D, open to researchers from all types of institutions and organisations worldwide, aimed at the increasingly important area of communication technology. The Journal''s emphasis is particularly on the issues impacting behaviour at the system, service and management levels. Published twelve times a year, it provides coverage of advances that have a significant potential to impact the immense technical and commercial opportunities in the communications sector. The International Journal of Communication Systems strives to select a balance of contributions that promotes technical innovation allied to practical relevance across the range of system types and issues. The Journal addresses both public communication systems (Telecommunication, mobile, Internet, and Cable TV) and private systems (Intranets, enterprise networks, LANs, MANs, WANs). The following key areas and issues are regularly covered: -Transmission/Switching/Distribution technologies (ATM, SDH, TCP/IP, routers, DSL, cable modems, VoD, VoIP, WDM, etc.) -System control, network/service management -Network and Internet protocols and standards -Client-server, distributed and Web-based communication systems -Broadband and multimedia systems and applications, with a focus on increased service variety and interactivity -Trials of advanced systems and services; their implementation and evaluation -Novel concepts and improvements in technique; their theoretical basis and performance analysis using measurement/testing, modelling and simulation -Performance evaluation issues and methods.
