Multiplexing and demultiplexing methods are crucial for meeting these requirements as they allow more than one data stream to be transmitted using the same channel. Demultiplexers′ design and implementation can be studied based on scalability, hardware efficiency, and timing aspects for various FPGA platforms. This paper introduces the hardware architecture of demultiplexer structures from (1 × 2) to (1 × 64) in the realm of reconfigurable computing. In this study, the architectures are designed with VHDL in Xilinx ISE 14.7 and tested via behavioural simulation, RTL synthesis and hardware resource estimation on various FPGA platforms. The novelty of the paper is presented in the scalability analysis of demultiplexer architectures through the linear growth in the number of logic resources utilised as the output dimension increases in different FPGA families. Main performance metrics like propagation delay, slice utilisation, LUTs and I/O are measured and compared for Virtex 5, Virtex 6, Spartan 3E and Spartan 6 FPGAs. It is shown that the proposed demultiplexer architecture scales well in the number of resources required and has no overhead, which makes the design scalable and suitable for implementation of large-scale routing circuits. Modern FPGA architectures have shown great improvement in terms of timing without any resource overhead, thus being more advantageous for high-speed computing systems. This paper makes a comparative analysis of the scalability of the selected Xilinx FPGA families and allows resource and timing analysis of the large-scale demultiplexers from (1 × 2) to (1 × 64).","PeriodicalId":54944,"journal":{"name":"International Journal of RF and Microwave Computer-Aided Engineering","volume":"2026 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/mmce/3208346","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149145739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four metaheuristic optimization techniques—Mountain Gazelle Optimization (MGO), Moth Flame Optimization (MFO), Sine Cosine Algorithm (SCA), and Multi-Verse Optimization (MVO)—have been employed to extract model fitting parameters. Model performance and suitability were evaluated by assessing fitting accuracy with DC I–V measurement data. This study showed that the models used accurately predict the characteristics of GaN HEMTs on sapphire and SiC substrates. The Statz model showed the acceptable performance of the devices on Si substrates. On the other hand, the models by McCamant, McNally, and Memon, Angelov, and Tajima always worked well on Si substrates, giving them a high fitting accuracy. The Statz, McCamant, Tajima, and McNally do not explain the electrothermal performance on the diamond substrate, exhibiting unphysical extracted parameters, which is not possible. The Memon model still works well for diamond′s better performance and breakdown properties.

This model obtains new unit cell structures and corresponding electromagnetic (EM) responses from simple probability distributions in the latent space to achieve better results. The semisupervised scheme combines supervised learning and unsupervised learning by sharing their respective weights of the encoders and decoders, reducing the number of labeled samples required to half the total number of samples. To improve the design freedom of unit cell structure, nonparametric modeling is introduced with binary images. To verify the proposed semisupervised generation model, a quasi-I–shaped pattern is selected as the basic unit cell structure for validation. After the trained generative model generates the optimal unit cell, a chessboard ultrawideband PCM with dimensions of 240 × 240 mm is designed, and the monostatic radar cross section is reduced by 10 dB from 10.2 to 18 GHz under the far-field normal incidence. The proposed model expands the freedom of the unit cell structure and improves the PCM performance using only a small number of labeled samples. Furthermore, compared with traditional generative models using the same training set, it shows significant improvements in both unit cell structure image generation and EM response prediction. This research provides an efficient new method for the intelligent design of microwave metasurfaces and supports their subsequent engineering applications.","PeriodicalId":54944,"journal":{"name":"International Journal of RF and Microwave Computer-Aided Engineering","volume":"2026 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/mmce/1829555","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148784329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It targets engineering datasets in which discrete design choices jointly affect continuous responses, making it suitable for data-driven RF, microwave, and millimeter-wave computer-aided design tasks such as antenna, circuit, and subsystem optimization.

Our approach focuses on classifying these gestures based on the antenna parameters of body-worn ultrawide band (UWB) antennas. Each finger gesture alters the electromagnetic field strength in a unique way, leading to distinct variations in the scattering parameters of the antenna. These variations can be harnessed to recognize and classify finger movements. In our experimental work, we implemented two sets of transmitting and receiving compact UWB antennas using FR4 and denim substrate materials. Datasets were collected from on-body antennas placed at three different locations on human subjects, capturing 10 distinct left-hand and right-hand finger gestures. The convolutional neural network (CNN) along with the crow search algorithm (CSA) technique and Extreme Gradient Boosting (XGB) are explored for presented finger gestures recognition and classification. The performance of the classification model and the effect of antenna placement locations have been evaluated. The results demonstrate that the superior classification performance was achieved by the proposed CNN-CSA with XGB model that possess 97.4% accuracy.","PeriodicalId":54944,"journal":{"name":"International Journal of RF and Microwave Computer-Aided Engineering","volume":"2026 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/mmce/8836225","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148616919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Designed to cover the LTE 4G band (2.50–2.69 GHz), the 5G N77 (3.30–4.20 GHz), and N78 (3.30–3.80 GHz) bands, as well as the upper 6 GHz band (6.425–7.125 GHz), the proposed filter uses a grounded patch etched with meander line resonators exhibiting inverted symmetry. Unlike conventional symmetrical resonators, this design introduces a coupled, inverted-symmetry resonator configuration integrated with a grounded patch. This proposed mechanism efficiently achieves a dual-band response by incorporating a notch band and enhances the upper stop-band rejection through the generation of two transmission zeros (TZs). The notch band of the proposed filter is allocated at 5.54 GHz to block the existing interference of the 5 GHz WI-FI, with an insertion loss of 35.1 dB and 10-dB notched fractional bandwidth of 17.33% (i.e., 4.93–5.89 GHz). This notch separates the wide bandwidth into two sub passbands, the first of which is allocated at 3.38 GHz with a 3 dB bandwidth of 68.63% (2.22–4.54 GHz) and the second sub passband, on the other hand, is assigned at 6.67 GHz with a 3-dB fractional bandwidth of 14.39% (6.05–7.01 GHz). Additionally, two TZs are detected in the upper stop band at 8.83 and 9.46 GHz, respectively. Note that, because of its close proximity with the 5 GHz WI-FI, the 5G N79 band (4.40–5.00 GHz) was not initially targeted. However, the compact designed filter is also covering part of it as well, making it an attractive device for 5G communication systems.","PeriodicalId":54944,"journal":{"name":"International Journal of RF and Microwave Computer-Aided Engineering","volume":"2026 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/mmce/4367857","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148467112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed antenna is designed to operate at 2.4 and 5.2 GHz bands, covering the ISM and WLAN bands. The antenna is fabricated on a felt substrate with a compact size of 30 × 50 mm2, ensuring wearability and comfort. To achieve dual-band performance and enhance antenna radiation, a 3 × 3 AMC array is employed beneath the textile monopole antenna. The overall size of the AMC reflector is 91.5 × 91.5 mm2, which is sufficiently large to act as an effective reflecting surface for both operating frequencies at 2.4 and 5.2 GHz. Each AMC unit cell is composed of an inner square patch and an outer square loop, designed to provide in-phase reflection characteristics at the two frequency bands. The measured impedance bandwidths of the proposed antenna are 10.66% (2.31–2.57 GHz) and 20.7% (4.46–5.49 GHz), with maximum gains of 7.24 dBi at 2.4 GHz and 7.12 dBi at 5.2 GHz. Moreover, the performance under bending is evaluated. The simulated specific absorption rate (SAR) of the proposed antenna with AMC reflector remains below the safety limit of 1.6 W/kg averaged over 1 g of tissue and 2 W/kg averaged over 10 g of tissue, confirming its safety for on-body operation.
