“…Some examples of its use are 802.15 wireless personal area networks (PANs) and IEEE 802.11 ad multiple gigabit wireless systems (MGWS), both of which are examples of high bandwidth LANs. Cloud gaming, Automatic vehicle communication (Md Hossain, 2023;Ullah et al, 2023;Rana et al, 2022) and THz imaging systems (Malhotra et al, 2018) are another ideal use cases for these antennas because of their high data speeds and short-distance propagation.…”

This paper presents a novel multiple-band elliptical patch octagonal antenna with and without proximity coupling. The frequency bandwidth and the requirement for high data throughput are always on the rise with today’swireless communication systems and therefore, multiband antennas are highly essential. A new elliptical patch octagon arrangement is proposed for use in this case as the efficiencies gained in using this form of an antenna are that it is capable of operating on multiple bands. Multi-band Elliptical Patch Octagon Antenna with and without Proximity Coupling of dimensions 15×25×1.6 mm3 is designed. A single-layer antenna operates at multiple frequencies from 10GHz to 300GHz, whereas a multi-layer antenna operates at 10GHz to 500GHz. For a sample at 28GHz, a Single-layer elliptical patch octagon antenna without proximity coupling antenna earned return loss (s11), gain and radiation efficiency of -21.38dB, 5.03dB and 90%, respectively. In order to enhance the bandwidth and gain of an antenna, a two-layer elliptical patch antenna with proximity coupling is designed whose return loss, gain and radiation efficiency are -24.5dB, 8.81dB and 88.69% at 29GHz frequency, respectively. The substrate employed for these two antennas is FR4, with a dielectric constant of 4.4 and a loss tangent (tanδ) of 0.002. Overall, this study provides a greater understanding of how proximity coupling influences the operation of multiband antennas, thereby paving the way to enhance the design and practical utilization of multiband antennas in today's wireless communication systems.

The exponential growth of the fifth-generation (5G) network gives businesses and universities a chance to turn their attention to the next-generation network. It is widely acknowledged that many IoT devices require more than 5G to send various types of data in real-time. In addition to 5G, several research centres are currently concentrating on 6G, which is expected to produce networks with great quality of service (QoS) and energy efficiency. Future application requirements will necessitate a significant upgrade in mobile network architecture. 6G technologies offer larger networks with lower latency and faster data transmission than 5G networks. This review presents a comprehensive overview of 6G networks which includes the novel architectural changes within 6G networks, recent research insights from diverse institutions, applications within the realm of 6G networks, and the key features associated with them. We also explored various technologies of 6G networks encompassing terahertz, visible light connectivity, blockchain, and symbiotic broadcasting, all of which contribute to the establishment of robust and socially integrated network structures. In this survey, we have focused on 6G network slices and discussed a detailed exploration of security and privacy concerns regarding the potential 6G technologies at the levels of physical infrastructure, connecting protocols, and service provisions, alongside an evaluation of current security strategies.

With the continuous emergence of the concept of 6G, the rapid development of industrial application scenarios, and the rise in demand for dedicated line services, there has been a strong and diverse demand for network capacity. The introduction of fine-granularity FlexE technology provides a new approach to addressing the diversification of Quality of Service (QoS) and the resource waste caused by large granularity (5 Gbps). However, the reduction in granularity leads to a significant increase in the number of slots, posing a serious challenge to deterministic latency assurance, especially in scenarios with dynamic fluctuations in service bandwidth. Sudden bandwidth variations can lead to service interruptions and fluctuations, resulting in uncontrolled network blocking rates. To address this issue, this paper proposes a traffic-driven proactive FlexE slot orchestration algorithm called PMFAN-GDSO. Based on this algorithm, bandwidth variations are calculated in advance based on the bandwidth change provided via the traffic prediction algorithm before service fluctuations occur. This avoids the time-consuming slot orchestration calculations and service abrupt changes. The real-world network datasets indicate that, based on our proposed algorithm, significant time savings of up to 46.8% are achieved compared to non-proactive prediction.
