ABSTRACTIn general, Multi‐User Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MU‐MIMO‐OFDM) enables multiple users to simultaneously communicate with a single base station using multiple antennas and OFDM modulation. Nevertheless, resource allocation challenges such as power management and delay optimization arise within MU‐MIMO‐OFDM systems, requiring sophisticated solutions to ensure efficient use of resources and optimal system performance. Thus, joint power and delay optimization‐based resource allocation using a Deep Convolutional Pyramid‐Dilated Neural Network (DCPDNN) with Red piranha optimization and Optimal Delay Scheduling conflict graphs Algorithm (DCPDNN‐RPO‐ODSCGA) in MU‐MIMO‐OFDM system is proposed in this presented research. The proposed mechanism is performed in two stages: power allocation and delay optimization. In the first stage, through a Deep Convolutional Pyramid‐Dilated Neural Network (DCPDNN), which aims to maximize throughput, the network resources are distributed to user equipment (UEs) based on power and transmission rate. To reduce the loss function, Red Piranha Optimization (RPO) is proposed to optimize the layers of DCPDNN. In the second stage, the Optimal Delay Scheduling conflict graphs Algorithm (ODSCGA) is proposed for the optimizing delay in the MU‐MIMO‐OFDM system. The multiracial envelope procedure and service curve for traffic flows in the uplink transmission are used in the ODSCGA approach to estimate the delay‐bound value. Ideas like the maximal weight independent set and optimal conflict graph are also utilized. The simulations of DCPDNN‐RPO‐ODSCGA were conducted using MATLAB software. Thus, the proposed approach has attained higher spectral capacity, higher fairness index, and increased cumulative distribution function (CDF), 29.74%, 32.98%, and 16.46% lower loss rate, 28.05%, 24.09%, and 17.45% improved energy efficiency, 15.09%, 13.78%, and 12.05% lower processing time than other conventional approaches like MPQM‐SCA, Hyb‐BF‐DSA, and SIA‐FDBD methods, respectively.

Abstract A Polydimethylsiloxane (PDMS) based antenna is designed for skin tumor detection. The antenna functions at 2.45 GHz with a bandwidth of 2.30–2.64 GHz working in the ISM (Industrial, Scientific, and Medical) band. The size of the antenna is 40 × 40 × 1 mm3. This antenna detects tumors in the skin by considering the variations in values of the E-field, J-surf, and H-field. Various analyses such as the distance between the patch and stacked layer skin phantom for different tumor sizes and input power to the antenna are changed and antenna performance is observed. A significant amount of changes is attained which denotes the presence of the tumor. The proposed antenna is fabricated and the corresponding results are analyzed in the Anechoic Chamber. The antenna has an efficiency of 99 % with a Specific Absorption Rate of 1.3846 W/kg which is lower than 1.6 W/kg as per the recommendations of FCC standard.

Abstract This research work presents an implantable antenna that operates at 5.8 GHz. By using a radiator with a loop-based design, the antenna can be made smaller. Radiator is made up of three connected rectangular loops. On the substrate’s back side, an I-shaped ground plane is used. As substrate and superstrate, polydimethylsiloxane (PDMS) with dimensions of 7 mm × 5 mm × 0.3 mm is used. The conducting sections are made using copper foil that is 30 µm thick. The suggested antenna is examined by the implantable medical device using realistic human scalp phantom models and a homogenous skin box. Simulated study revealed that it operates around 5.8 GHz with a bandwidth from 5.69 to 5.92 GHz. The specific absorption rate was 0.28 and 0.26 W/kg for skin box and human scalp phantoms, respectively, at 1 mW input power across 1 g volume tissue.

Microwave breast imaging (MBI) promises a more accurate and safer modality for breast cancer detection to provide information about breast tissues that uses longer wavelength low power signals when compared to other conventional techniques like X-ray mammography. This paper includes the performance analysis of slot loaded microstrip patch antennas suitable for breast cancer detection. Four types of antennas structures: without any slits, with truncated corners, with L shaped slots and square shaped slits arranged serially are designed with the help of FR4(dielectric constant = 4.4) as the substrate which is simulated using CST software. The designed antenna has been compared with conventional ones and results shows the superiority of designed antenna in terms of S11parameter, gain, directivity, return loss. The gain of the designed antenna is far superior to that of conventional antennas. As such antennas are used extensively for medical applications the measure of specific absorption rate (SAR) becomes very critical. It has been observed in the different structures that insertion of slits, slots and truncations helps to vary the resonant frequency of the antenna and helps in achieving circular polarization which is needed for medical applications. Optimum performance is achieved using the designed antenna in terms of gain, VSWR, return loss and the radiation limits were obtained which falls within limit of 1.6 W/kg as recommended by FCC.

This paper presents the design of single band microstrip patch antenna for 5G applications. Now a days, most of the fields are adopting the 5G technology to connect millions of devices together. This future technology can be used in smart buildings, machine communications (IOT), Robotics and Greater speed data transmission applications. For better communication between the devices, it is necessary to design a efficient antenna. Mostly 5G antennas are used in microwave as well as millimeter frequency bands. 3.5 GHz range which falls under the C-band which is the basis for the 1st implementations of 5G technology worldwide. The commercially available FR4 substrate which has the flame resistant property, have been used in this antenna with an overall dimension of 29.8 x 36x1.6mm3. The proposed antenna operates in the 5G bandwidth of 3.4-3.6 GHz with the resonating frequency of 3.5 GHz. The proposed 5G antenna had been designed and simulated in the ANSYS HFSS software. The resultant antenna shows the return loss -22dB at 3.5 GHz, good Sparameter, acceptable gain and radiation efficiency.

this paper, presents a polarization re-configurable antenna for 5G applications operating at 3. 5GHz for n78 band. A micro-strip fed rectangular patch antenna is used in this design. A slant rectangular slot is made into the patch to divide it into two parts. One part is connected to the strip feed and another part with gap made due to slot. The non fed part of the patch is connected to an E-shaped stub in a slant way similar to the slot. A PIN diode is placed into the slot to make connection in between the two parts. The PIN diode switching condition helped in shifting polarization from linear to circular vice versa, making the antenna suitable for 5G applications.
