  • Design of a Hilbert Curve Fractal MIMO Slot Antenna With Enhanced Bandwidth and Stable Radiation Patterns for Wi-Fi 7 and Wi-Fi 8 Applications Using Genetic Algorithm
    N. M. Mary Sindhuja, R. Sreelakshmy, Om Prakash Kumar, Muddineni Raveendra
    International Journal of Antennas and Propagation, 2026
    Next‐generation Wi‐Fi 7 (IEEE 802.11be) and Wi‐Fi 8 (IEEE 802.11bn) demand compact multielement antennas offering wide bandwidth, high isolation, and stable radiation within limited device space. Conventional MIMO designs often face strong coupling, narrow bandwidth, or low efficiency, restricting high‐throughput multilink performance. This work presents a Hilbert curve fractal (HCF) four‐port MIMO slot antenna that leverages fractal self‐similarity to extend the surface current path and excite multiple resonant modes within a compact size. The HCF slot supports TE 20 and TE 40 modes—TE 20 excites the lower 5‐GHz band (5150–5945 MHz), while TE 40 generates a higher‐order resonance in the 6‐GHz band (6150–7150 MHz). Merging both bands allows for broadband dual‐band operation. A defective ground structure reduces surface waves and improves isolation, while a genetic algorithm optimizes geometric parameters for wideband impedance matching across all four ports. The improved design has a measured bandwidth of 2125 MHz (5.0–7.125 GHz), a peak gain up to 6.51 dBi, radiation efficiency greater than 82%, and isolation up to −32 dB. The low ECC (< 0.005) and 10‐dB diversity gain make it suitable for durable, high‐capacity Wi‐Fi 7, Wi‐Fi 8, and future sub‐6‐GHz communication systems.

  • Isolation Enhancement Based on TM010 and TE30 Mode Characteristics in a Patch Antennas Using Genetic Algorithm Optimization for Ku-Band Applications
    Muddineni Raveendra, U. Saravanakumar, P. Padmaloshani, P. Saam Prasanth Dheeraj, Anand Anbalagan, et al.
    International Journal of Antennas and Propagation, 2025
    This paper proposes a novel technique to enhance isolation in rectangular patch antennas by leveraging the mode characteristics of TM010 and TE30 to achieve better than −40 dB between the transmitter and receiver with dual‐polarization features. The primary innovation of this work lies in achieving significant isolation enhancement solely by combining two resonant modes with orthogonal polarizations, without incorporating any additional design elements such as parasitic components or decoupling structures. To validate the isolation enhancement based on these mode characteristics, a pair of rectangular transmitter and receiver patch antennas was designed to operate in the frequency range from 14 to 14.25 GHz. The transmitter antenna was designed using the TM010 mode with horizontal polarization, while the receiver antenna used the TE30 mode with vertical polarization. The design utilized a Rogers 3003 series dielectric substrate with a dielectric constant of 3.3 and a loss tangent of 0.003. A genetic algorithm with tournament selection and a multiobjective function was applied to optimize key performance metrics, such as impedance matching, bandwidth, and gain. Following successful optimization, the simulated results were validated against measurements, showing excellent agreement and confirming the accuracy of the proposed antenna design.

    Innovative antenna designs are necessary to meet the high-speed, low-latency needs of 6G and next-generation wireless networks. Because of problems with scalability, efficiency, and flexibility, the performance of standard antenna design approaches degrades in dynamic conditions. Real-time network optimization, interference, and energy usage are additional issues with these systems. The AI-driven antenna design is based on ML and DL techniques. The antenna's architecture is optimized using an AI-based system that continuously learns and adapts to the evolving behavior of the network. It optimizes antennas in real-time by using data preprocessing, feature extraction, and ML models. When compared to the newest technology, it exhibits improvements in throughput, latency, energy usage, and signal quality. These include a 35% reduction in energy consumption, a 40% reduction in latency, and a 20% increase in throughput. The results show that the proposed system can increase network performance and efficiency, which supports the proposed system's potential applicability for wireless communication in 6G and beyond.

  • Investigation of Split Ring Resonator Based Rectangular Micro-Strip Patch Antenna for Radar Communication

    Journal of Advanced Research in Applied Sciences and Engineering Technology, 2024
    The advent of antenna technology has greatly influenced the field of wireless communication. In this paper, a novel rectangular microstrip patch antenna with split ring resonators is presented. It is intended for use in the X-band, which normally operates between 8 and 12 GHz. Split ring resonators are incorporated into the radiating patch to increase gain and frequency bandwidth. Based on Rogers TMM 10TM, a dielectric material with a relative permittivity of 9.8, the antenna is made to operate at 10.4 GHz in the X-band. Several factors, such as S-parameters, radiation pattern, Voltage Standing Wave Ratio (VSWR), gain, and directivity are used to assess the performance of the proposed antenna. The design and simulation of the antenna need the usage of High-Frequency Structure Simulator (HFSS) software. The findings imply that the suggested antenna configuration has an efficiency of 93.5% and is proved to be an excellent candidate for Radar Communication because of its wide frequency bandwidth and other performances.
  • Advancing Heart Attack Prediction: Machine Learning for Enhanced Cardiac Risk Analysis
    Shailendra Kumar Mishra, R. Sreelakshmy, Gaurav Kumar, Dheeraj Kumar, Sujeet Kumar
    Pioneering Approaches in Data Management, 2024
    Cardiac arrest is one of the most frequently occurring causes of death worldwide. In this disease, the heart normally fails to provide enough blood to other regions of the body to allow them to perform their regular functions. It is tough for doctors to forecast cardiac arrest because various medical and physical habits are taken into consideration for forecasting cardiac arrest. Because the list of parameters is large, it is important to automate the procedure to avoid manual mistake, enhance medical efficiency, and reduce costs. The paper presents Explanatory Data Analysis (EDA) and feature engineering of a data set on the basis of observations. The model uses various Machine Learning (ML) algorithms such as catBoost, Logistic regression, k-Nearest Neighbors, etc. to predict heart failure. In this comparison study, the research paper examines the performance of various machine learning algorithms. The model's performance is best on catboost. Analysing tools such as f-1 score and ROC-curve are drawn to evaluate the algorithm's efficiency.

    In this study, we suggest short-range, lightweight 6th subsequent generations (6 G) in-X network parts as a valuable radio concept responding to the demanding connectivity requirements of new applications like wearable control of arms equipped with robotics and critical on-body gadgets which include wireless heart pacemakers. The main requirements of ultra-high fidelity (exceeding 6 nines when) and sub-millisecond delay at all spatiotemporal contexts demand powerful radio systems contrary to fading and interference. Our study thoroughly explores technology drivers and methods for interference reduction in 6 G in-X subsidiary networks. The proposed methods include blind-repetition at pseudo-random frequency shifts and environment-aware tools for interference control through dynamic channel sharing. Additionally, we suggest two novel enhancements: real-time repeat order adaptation using current channel dynamics and preemptive packet duplication, during which subnetworks that are duplicate signals on a third channel group upon spotting possible nearby subnetwork interference. Simulations in an industrial workplace setting with mobile in-X subnetworks, by employing 3GPP-defined models, show the need for large internet connectivity, packet repeats, and environment-aware interference synchronization to achieve low packet loss percentages and sub- $100 \\mu$ s delay. The suggested improvements show large packet loss rate decrease for systems with life times $\\gt 2$ cycle times.
