Abstract

This article addresses the critical and timely task of employing strike FPV drones in kamikaze mode to neutralize enemy counter- This study presents a comprehensive analysis of the design and optimization of MIMO antenna systems, which are fundamental to modern wireless communication technologies such as WiMAX and 5G. MIMO technology enables the simultaneous transmission of multiple independent data streams by employing multiple antennas at both the transmitter and receiver. This significantly enhances network capacity, spectral efficiency, and overall communication reliability, making MIMO a key enabler for high-speed and high-capacity wireless networks. The advantages of MIMO systems are particularly evident in urban environments, where multipath propagation and interference present considerable challenges to signal integrity. By leveraging spatial diversity, MIMO mitigates these issues, ensuring robust signal reception even in complex propagation conditions. Moreover, MIMO contributes to increased energy efficiency, leading to more sustainable and cost-effective network operations. This is especially relevant for next-generation wireless networks, where power consumption and spectral optimization are crucial factors in maintaining high system performance. A critical aspect of MIMO system optimization is the refinement of key structural parameters, including element isolation, radiation efficiency, and antenna array geometry. The results obtained in this study demonstrate that the optimized MIMO system achieves an extremely low envelope correlation coefficient (ECC<0.0002), ensuring minimal interference between antenna elements. Additionally, the system exhibits a high diversity gain (DG>9.991 dB), which enhances link reliability and signal robustness. Furthermore, the optimized configuration minimizes capacity loss (CCL<0.1 bit/s/Hz) while maintaining an efficient total active reflection coefficient (TARC<–10 dB) and an optimal mean effective gain (MEG ranging from –6.2 dB to –7 dB). These performance indicators confirm the effectiveness of the proposed design in delivering high data throughput, stable connectivity, and improved system reliability, all of which are essential for WiMAX and 5G technologies operating in high-density user environments and under heavy traffic conditions.

In addition to structural optimizations, adaptive beamforming techniques further enhance system efficiency by dynamically adjusting antenna radiation patterns based on real-time channel conditions. This approach not only improves spectral utilization but also maximizes signal strength and reduces interference, leading to better overall network performance. The findings of this study provide valuable insights for the development of next-generation wireless networks, offering improved connectivity, optimized spectral efficiency, and enhanced system resilience in dynamic communication environments.
