DESIGN OF 60GHZ ANTENNA FOR 5G COMMUNICATION SYSTEMS

Abstract

5G technology was developed to transform mobile communication through fast data rates, reduced latency, and enhanced network capacity. Transitioning to higher frequencies, especially in the millimeter wave region, has presented issues related to signal path and propagation loss. To address these limitations, a systematic examination is being conducted to explore the use of the 60GHz frequency band. This action aims to overcome existing challenges in implementing 5G and prepare the foundation for upcoming generations such as 6G. Utilizing 60GHz frequencies can enhance the capabilities and possibilities of wireless communication, leading to a more efficient and productive network. This study presents a proposal for a microstrip patch array antenna consisting of four components, designed specifically for 5G wireless applications, with a particular emphasis on the utilization of the 60 GHz millimeter-wave spectrum. The emphasis of the design is on the choice of a single microstrip patch antenna as the primary radiating component using Rogger RT 5880, Teflon, and LTCC A6M as a dielectric substrate. The antenna is designed to function exceptionally well in a wide range of weather situations while simultaneously guaranteeing robustness and dependability. This master thesis highlights the notable performance variations across Roggers RT5880, Teflon, and LTCC A6M substrates when designing single, two, and four-element patch antenna arrays for 5G communication systems at 60 GHz. The design approach makes use of Computer Software Technology (CST) Microwave Studio, which integrates different dielectric substrates Roggers RT5880, Teflon, and LTCC A6M characterized by a relative permittivity of 2.2, 2, and 5.9 respectively. LTCC A6M substrate offered high-quality antenna performance results when arranged in an elements array using single layer substrate. And Teflon offered better results when arranged in a single and two-elements array. However, thefinal results emphasize Roggers RT5880 as the best substrate material due to its outstanding characteristics like high gain, high directivity, broad bandwidth, input impedance matching,and compact size. The findings offer useful recommendations for enhancing antenna designs and selecting substrates, ultimately promoting the creation of high-performance antennas customized for modern wireless communication applications.
