RAMDANI AbderahmaneAISSAOUI mohammed2024-09-102024-09-102024https://dspace.univ-eloued.dz/handle/123456789/34067Master's theses: specializing in wired and non-wired communicationsThis thesis presents a comprehensive investigation into patch antenna array design for 5G networks, with a focus on millimeter-wave (mmWave) frequencies. Beginning with an exploration of the evolution of mobile communication and an in-depth examination of antenna theory, the thesis transitions to practical implementation in chapter 3, utilizing High-Frequency Structure Simulator (HFSS) for design and optimization. Through meticulous analysis and simulation, various design methodologies, optimization techniques, and simulation tools are explored to develop efficient and high-performing antenna arrays. Recognizing the need for high gain (over 12 dBi) in 5G systems. Two-element and four-element antenna array designs are presented, successfully achieving the target gain of over 12 dBi at both resonant frequencies (36 GHz and 38 GHz). The culmination of this research contributes to the advancement of antenna technology, providing valuable insights and practical guidance for researchers, engineers, and practitioners seeking to harness the full potential of 5G communications in the mmWave era.This thesis presents a comprehensive investigation into patch antenna array design for 5G networks, with a focus on millimeter-wave (mmWave) frequencies.
