A master’s thesis in the College of Electronics Engineering, Department of Communications Engineering, by student Noor Sabah Asaad Saleh, titled “Investigation into Multi-Antenna Techniques for the Future 6th Generation (6G) Communication”, explored the study of multi-input multi-output (MIMO) antennas suitable for future 6G communications.
The thesis aimed to propose a hexagonal loop-shaped MIMO antenna operating in the terahertz frequency range. The antenna was designed using graphene due to its unique property of enabling high-speed transmission in the terahertz frequency range. The design began with a single antenna and evolved into a two-element MIMO antenna, followed by a four-element antenna, and finally an eight-element antenna with two different configurations: straight and angled.
The issue of interference between antennas was resolved using various methods such as applying a Defected Ground Structure (DGS), a Neutral Line (NL), and parasitic decoupling methods to enhance performance between the radiating elements. Extensive parametric studies were conducted to investigate the importance of using these techniques. Additionally, the performance of the proposed MIMO antennas was studied in terms of various metrics using several software tools, and the diversity performance was evaluated and compared with other works.
The results demonstrated high performance of the proposed MIMO design for next-generation applications. A research paper based on the study was published in a Scopus-indexed journal:
Journal of Telecommunications and Information Technology (JTIT).
