This will subsequently promote a global industrial integration. Wireless communication will be ubiquitous in all areas of future society, supporting novel applications with various performance requirements, such as immersive- or interactive-experience applications requiring a large bandwidth, autonomous driving and vehicle-to-everything applications requiring ultrahigh reliability and ultra-low latency, and applications for industrial Internet requiring massive machine-type connectivity. Facing the challenges of the post-Moore and post-pandemic era, wireless communication needs breakthroughs in network architecture to improve the intelligence, security, robustness, bandwidth, and heterogeneity. https://link.springer.com/article/10.1631/FITEE.2210000 领域二低轨卫星通信遥感融合：架构、技术与试验 Communication and remote sensing integrated LEO satellites: architecture, technologies and experiment PENG Mugen, etc. 电信科学, 2022, 38(1):13-24 低轨卫星系统是获取空间信息和破解宽带数字鸿沟的重要基础设施之一,通信与遥感融合是解决现有遥感和通信分治、卫星重置、应急业务响应不及时等问题的有效途径。概述了低轨通信和遥感卫星系统的现状,针对通信和遥感融合需求,提出了通信遥感融合方案及体系架构,阐述了基于该体系架构的硬件组成及融合试验方案,最后探讨了相关挑战和未来发展。 Low earth orbit (LEO) satellite system is one of the most important infrastructures to gather spatial information and break the broadband digital divide. The integration of communication and remote sensing is an effective way to solve the existing problems of system independence, satellite resource waste, and late response to emergency service requests. Firstly, the status of communication and remote sensing in LEO satellite systems were outlined, and then a communication and remote sensing integrated scheme and architecture were put forward to meet the integration requirements. In addition, a hardware composition and corresponding experiment based on this architecture was introduced. Finally, the relevant challenges and future development were discussed. http://www.infocomm-journal.com/dxkx/CN/10.11959/j.issn.1000-0801.2022021 领域三用于5G通信的紧凑型二元MIMO天线 A compact two elements MIMO antenna for 5G communication Ashfaq Ahmad, etc. Scientific Reports, 2022, 12 This study presents a simple, miniaturized, and low-profile multiple-input multiple-output (MIMO) antenna operating at 29 GHz with reduced mutual coupling between the antenna elements for futuristic 5G communication. The proposed design employs two radiating elements with slits in the radiators to produce high isolation among the antenna radiators. The MIMO antenna maintains a compact structure of 11.4 × 5.3 mm2, which is the smallest size compared to previous 5G antennas. Roger’s 4350B laminate was employed as a substrate material. At 29 GHz, low mutual coupling of - 36 dB, low envelope correlation coefficient (ECC < 0.001), and high diversity gain (DG > 9.8 dB) are achieved. The proposed design is examined in terms of the S-parameters, diversity gain, radiation pattern, and envelope correlation. Compared to the straight antenna element, an improvement of - 20 dB is observed in the isolation for both the simulated and measured results. https://www.nature.com/articles/s41598-022-07579-5 领域四适用于72.5-81GHz频率范围片上应用的一种基于超材料的新型天线 A novel metamaterial-based antenna for on-chip applications for the 72.5–81 GHz frequency range Karen N. Olan-Nu?ez, etc. Scientific Reports, 2022, 12 In this paper we present a novel metamaterial-based antenna simulated using HFSS. The unit cell parameters were extracted using periodic boundary conditions and wave-port excitation. The metamaterial is magnetically coupled to the CPW line, the induced current in the hexagonal ring gives rise to a field perpendicular to the incident one. The antenna can be modeled by an LC circuit. This design achieves a significant impedance bandwidth of 8.47 GHz (S11 = -10 dB from 72.56 GHz to 81.03 GHz), and a minimum return loss of -40.79 dB at 76.89 GHz, which clearly indicates good impedance matching to 50 Ω. The proposed antenna offers gains from 4.53 to 5.25 dBi, with radiation efficiencies better than 74%. Compactness, simple design layout, a novel design, and good radiation characteristics for this antenna are the main contributions of this work. The antenna can be built on top of a 300 um thick silicon wafer, for application on HR-SOI-CMOS technology. When compared to other antenna designs for the same frequency band, the proposed antenna achieves very good performance. This design is suitable for the reception stage of long-range automobile radar systems, due to its wide HPBW, as well as E-band applications, such as backhaul systems. https://www.nature.com/articles/s41598-022-05829-0
