Engineering, 2024 Cataloged from the PDF version of the internship reportIn this thesis 1*4 antenna array has been proposed for 28Ghz (n257) frequency band. Deploying an antenna array is essential in 5G millimeter-wave scenarios to address challenges such as path loss, multi-path fading, and to improve network capacity. It is crucial to evaluate the limitations of conventional communication, such as restricted coverage, interference, and slower data rates, which may be efficiently resolved by an array. A metamaterial loaded antenna system that is attaining a gain of 10.81 dB, 11.76 dB directivity and 91.4% efficiency at a frequency of 28 GHz. This design showcases technological robustness by using planar microstrip technology on a 1.6 mm thick Rogers-5880 dielectric substrate with a relative permittivity of 2.2. The array's specific features determine its compatibility for smooth integration into the millimeterwave (mm-Wave) frequency range..enThesis
