Recently the Metaverse has received enormous attention around the world. The advanced metaverse will be a more realistic environment with greater specific and subtle interconnections, with less race, gender, and even physical impairment, all of which would be immensely helpful to society. However, metaverse is still in its infancy, with a lot of room for improvement. The industry has already begun to prepare for the metaverse’s enormous potential, supported by frenzied investment, yet there are few talks on metaverse in academia to scientifically lead its growth. In this paper, we present a metaverse design that adopts a global approach to technology, communication, and the environment. We propose an AI-driven metaverse model that might be deployed to realize the promise of model-based systems engineering in the near future. Finally, we offer research questions that should be taken up by academia to further the metaverse.

A novel compact CPW-fed fern fractal monopole antenna is presented. The proposed antenna covers different bands of GPS (Global Positioning System) L5 (1176 MHz), Industrial, Scientific and Medical (ISM) band (2.45 GHz), and wireless local area network (WLAN) 5.2 GHz. The small physical size and multiband operations are significant in the design of modern antennas. Fractal geometry provides simultaneously a good method for achieving the desired miniaturization and multiband performances. The proposed antenna is designed on an FR4 substrate with a permittivity of 4.4 and a thickness of 1.6mm with the overall size of an antenna as 90mm×60mm×1.6mm. The antenna works for frequency ranges of 1.07–1.18 GHz, 2.4–2.7 GHz, and 4.2–5.4 GHz with gains of 1.4 dBi, 3.0 dBi, and 5.8 dBi, respectively.

Millimeter wave (mmWave) frequency band has the potential to become one of the most influential contributors to fulfill the need of faster wireless communications with increased capacity. Multiple input multiple output (MIMO) technique, which is a candidate technology for mmWave wireless communication system, enables designing of communication channels utilizing spatial multiplexing. This paper represents an analysis of 2×2 and 4×4 MIMO channel characteristics for Urban Micro (UMi) cell scenario at 28 GHz. Main two performance indicators, those were considered in the paper are condition number and rank of the channel matrix in non-line of sight (NLOS) environment. Other parameters, those were considered, are Power Delay Profile (PDP), Outdoor to Indoor (O2I) penetration loss, and antenna spacing. The performance comparison between 2×2 and 4×4 MIMO channel for both Co-Polarization (Co-Pol) and Cross-Polarization (Cross-Pol) of antennas are also analyzed. The channel modelling was done using an open source channel simulator NYUSIM.
