This paper presents a study of a low-profile printed microstrip UWB antenna in the frequency range of 4-15 GHz. The results of investigation of the characteristics of the UWB antennas (VSWR, gain, Radiation pattern characteristic, RCS) with different geometry of ground surfaces are presented. Several models of antennas are made, the comparative analysis of calculation results of experimental samples with their numerical models is carried out. A good agreement between the results of mathematical modeling and experimental characteristics of real antenna samples is shown. The influence of the substrate shape on the reduction of scattering characteristics of antennas is analyzed. Applying the presented topologies of the ground surface, makes possible to extend the operating frequency range of the antenna without using additional matching elements and reducing antenna dimensions. For this model, the operating frequency range was 2.7 GHz to 13 GHz, and it is realized only by modifying the shape of the ground surface. © 2024 IEEE.

This paper presents the results of modeling of a low-profile ultra-wideband microstrip monopole antenna with CSRR resonator in the range of 2-18 GHz. The antenna characteristics were calculated using specialized CAD software Altair FEKO. The paper presents the results of modeling and analysis of an ultra-wideband microstrip antenna with emphasis on the effect of including a double open-loop resonator on its characteristics. The performance of different antennas is compared. The results show that the inclusion of a CSRR resonator in the antenna design leads to the appearance of rejection zones, the position of which can be changed by varying the size of the resonator. In addition, real antenna designs with and without CSRR resonators have been developed and tested, and the performance of real antenna designs has been compared with numerical simulation results. Measurements of antenna directivity characteristics, frequency dependences of reflection coefficient and input impedance were carried out at the Center for Collective Use "Applied Electrodynamics and Antenna Measurements" of the Southern Federal University. The results of experimental studies fully correlate with the results of modeling, and confirm the appearance of the rejection zone in the frequency region of 6 GHz due to the use of CSRR resonator. © 2024 IEEE.

ISBN: (纸本)9798350370447

In this paper, the results of a simulation of a dualband 5G antenna for wireless power transmission using Altair FEKO software are presented. Frequency bands were selected as 4.4-5.0 n 5.15-5.925 GHz, these bands are declared by standard 5G Sub-6 GHz (bands n79 and n46). The construction of the antenna was developed as complex-shaped patch antenna. Research of the main characteristics was made, and also the parameterization task was solved for this antenna by the criterion of minimizing the SWR. Patch has got SWR 1.058 and 1.273 at bands we're studying. At the end, the prototyping of this model was carried out. Experimental studies of the frequency dependence of the SWR of the antenna found out that the results of nature measurement don't confront the results of computer simulation. © 2023 IEEE.

The influence of the spatial correlation value on the bit error rate of the MIMO-OFDM communication system when using the adaptation algorithm is investigated [3]-[5], [7]. A mathematical model of a correlated communication channel (Kronecker model) and a method for obtaining a model of a correlated communication channel from a communication channel without correlations are presented. The algorithm is modeled and BER curves (bit error rates) are obtained for the MIMO-OFDM communication system when using the adaptation algorithm and without it with spatial correlations of different magnitude (weak and strong). The results obtained indicate that the use of adaptation makes the detector of the receiver of the communication system more resistant to the influence of spatial correlation and allows for greater gains on the entire curve of the bit error rate. © 2023 IEEE.

To improve the capacity by a factor of the minimum number of transmit and receive antennas, additional transmit and receive antennas can be utilized to create multiple-input multiple-output (MIMO) channels. Wideband transmission may utilize MIMO-OFDM, an orthogonal form of frequency division multiplexing (OFDM) for MIMO channels, to reduce inter-symbol interference and increase system capacity. In order to increase network performance when non-line-of-sight communications, which are prevalent in densely populated areas, occur, this research offers a suitable adaptive algorithm to be employed in wireless networks based on MIMO OFDM system. On the system's performance, the impacts of multiple pathways signal attenuation, Doppler shift, and various mobility speeds were studied. Utilizing BER, SNR, and noise components, mathematical models analysis of adaptive modulation in MIMO systems is handled. According to simulation data, the adaptive method would increase throughput. Implementation of adaptive algorithms has an improving effect on noise immunity when processing signals in a receiving system under the circumstances of multi-path signal propagation, it can also be concluded. © 2023 IEEE.

The emergence of a new type of information infrastructure that has the potential to support a variety of advanced healthcare services is being advanced by rapid advancements in information technology, telecommunications, and, more specifically, wireless and mobile communications - and their convergence ('telematics'). In order to improve network performance in the case of non-line-of-sight communications, which are typical in urban environments, the objectives of this paper is to provide an appropriate adaptive algorithm for use in telemedicine communication based on MIMO OFDM WiMAX (MIMO - Multiple Input Multiple Output, OFDM - Orthogonal Frequency-Division Multiple Access, WiMAX - Worldwide Interoperability for Microwave Access). In comparison to traditional wired methods, OFDM WiMAX technology is today regarded as one of the most widely used technologies for delivering faster implementations and lower costs for broadband wireless connectivity in urban areas. MSE, SNR, and noise components are used to perform the mathematical model analysis of the adaptive algorithm in MIMO systems. The throughput of medical images was improved, according to simulation results, using the adaptive algorithm. The experiments verified no data loss during wireless communication. It can also be concluded that the use of adaptive algorithms under conditions of multipath signal propagation has a better result on noise immunity. © 2023 IEEE.

The influence of active interference on the bandwidth of a MIMO-OFDM communication system is studied using an adaptive signal processing algorithm in the receiver. Theoretical calculations of the features and characteristics of MIMO systems are presented, and a mathematical model for calculating the throughput of MIMO systems is presented. Experiments on signal detection in a communication channel with and without adaptation using the Viner criterion and the presence of interference with one type of modulation (QPSK) are presented. The results show that the adaptation allows us to achieve an increase in throughput along the entire line of the dependence curve and for all SNRs, even in the presence of interference. © 2023 IEEE.

The article presents an algorithm for pre-processing images of the map of the underlying surface to reduce background noise. The aim of the development is to create an algorithm for a fast and highly efficient system for processing noisy areas of the underlying surface map. Methods for averaging images using filters are considered. The object of the research is the methods of preprocessing and filtering of map images. Preprocessing is an important step for analyzing the map of the underlying surface in order to eliminate image defects that prevent obtaining complete information about objects, areas of interest taken from the UAVs. An image preprocessing algorithm based on a median filter using a deep learning neural network has been studied and its software implementation has been developed. The efficiency of the developed algorithm was evaluated using two quality criteria, such as the peak signal-to-noise ratio and the standard error criterion. © 2023 IEEE.
