Flexible, Highly Thermally Conductive and Electrically Insulating Phase Change Materials for Advanced Thermal Management of 5G Base Stations and Thermoelectric Generators

Phase change materials have a high success in thermal control applications due to their high capacity of heat storage and isothermal behavior during phase transition. We present coreu2013sheath nanocomposites with an interconnected and linked boron nitride nanosheet network by combining coaxial electrospinning, electrostatic spraying, and hot-pressing in this series. At a low BNNS loading, the advanced PCN films display an extremely high thermal conductivity of 28. 3 W mu22121 Ku22121, which also provides the PCNs with high enthalpy, excellent ductility, and increased fire retardancy. The PCNs also provide effective cooling systems on 5G base station chips and thermoelectric generators, displaying promising thermal management applications on high-power density equipment and thermoelectric conversion units. Successfully produced a core-U2013sheath structural phase change nanocomposite with aligned and overlapping interconnected BNNS networks. The PCN shows the possibility of extensive use in 5G base stations and thermoelectric generators.

Reconfigurable SIW antenna at 28/38 GHz for 5G applications

A Substrate Integrated Waveguide antenna has been introduced here as a single component and can be tweaked betwixt 28 and 38 GHz. A change is made in the antenna's resonant frequency of 28-u201338 GHz by turning off one of the two PIN diodes, which had been used as switches. This reconfigurable SIW antenna comes with a variety of configurations, including a K-type connector input. At 28 GHz, the antenna responds with 7. 16 dBi of gain and 94% efficiency when S1 is off and S2 is enabled. When S1 is on and S2 is off, the antenna responds with a gain of 10 dBi and an efficiency of 88% at 38 GHz. The antenna increases by 7. 09 dBi for 28 GHz when every PIN diode is turned off, but it rises by 10. 7 dBi for 38 GHz.

Harris Hawks optimization based hybrid deep learning model for efficient network slicing in 5G network

Next-generation and sixth-generation networks that have been specifically developed by Newly devised are extremely reliable, low latency, dependable, and versatile. These next-generation networks differ from traditional networks. Network slicing is a key component of 5G and 6G networks, and it's important in delivering the aforementioned services over the same physical network. Operators can run multiple network instances on the same network as a result of network slicing. This paper aims to produce an efficient network-slicing algorithm based on a mixed learning algorithm. We developed a methodology with three primary phases: loading the database, optimization using HHO, and slicing classification using a hybrid deep learning framework as a result. For the best hyperparameter tuning, we load the files and apply HHO optimization for the first hyperparameter tuning. The following is the introduction of HHO-CNN+LSTM, a convolution neural network-based deep learning system with long-term memory applied.

Downlink Electromagnetic Field Exposure Levels in Pre-5G and 5G Ultra-Dense Mobile Networks

The 5G new radio is a new radio access network technology that can be used for ultra-high speed, ultra-high reliability, and ultra-low latency mobile communications. However, the public is also concerned about the electromagnetic field exposure from 5G networks due to the potential health danger. In particular, both urban macro cell and urban micro cell scenarios are considered in this research. Compared to that of the LTE network, the 5G network's exposure is similar to that of the LTE network in Then. A number of studies on the safe distance between 5G base station and the user equipment to minimize health risk are also presented.

Two-Element MIMO Antenna with Polarization Diversity for 5G Application

In this paper, a two-element multiple-output antenna with circular polarization diversity for sub-6 GHz application is recommended. As an inverted L-shaped strip and an L-shaped strip are added to the patch's resonating edge, the axial ratio bandwidth expands even more. With a distance of about u03b /4, a two-element MIMO antenna with a circular polarization diversity configuration is produced. With a diversity gain score near to 10. 10, the envelope correlation coefficient is less than 0. 005 with a diversity gain score close to 10. The antenna can be used in a 5G sub 6 GHz band and wireless communications.

High Gain Multiband Microstrip Patch Antenna for mmWave 5G Communication

Because of the sundry appealing highlights of the millimeter wave radio's ability to offer multi-gigabit transmission rates, millimeter wave radio has dragged in a lot of money from the academic, industry, and ecumenical normalization organizations.

Multiband Dual-Layer Microstrip Patch Antenna for 5G Wireless Applications

Due to its lightweight, compact, and rigid design, small volume, and little sensitivity to manufacturing tolerances, a microstrip patch antenna is suitable for 5G wireless communications. To avoid the use of multiple antennas, communication networks have often required multiband antennas in the last few years. The improved antenna for 5G applications is highly effective in the frequency bandwagon of 0 to u201310GHz. Here, two-layer geometry is used with one driving patch and another parasitic patch.
