Abstract:

In recent years, the rapid advancement in terahertz (THz) technology has necessitated the development of high-performance antennas capable of operating efficiently at these frequencies. Graphene-based microstrip nanopatch antennas represent a promising solution due to their unique material properties and potential for high-frequency applications. This study explores innovative and cutting-edge antenna geometries designed to enhance the performance of graphene-based microstrip nanopatch antennas at THz frequencies.

We investigate several novel geometries, including fractal, metamaterial-inspired, plasmonic, and hybrid structures, to optimize key performance metrics such as gain, bandwidth, efficiency, and radiation pattern. Fractal geometries are analyzed for their multi-band capabilities and compact design, while metamaterial-inspired designs are evaluated for their high gain and extended bandwidth. Plasmonic structures are examined for their potential to achieve nanoscale field concentrations and high gain, though challenges in bandwidth and efficiency are considered. Hybrid structures, combining various geometries and materials, are explored to leverage their integrated benefits and address specific performance requirements.

The study employs advanced simulation tools such as CST Microwave Studio and HFSS to model and analyze these geometries, followed by optimization of critical parameters. Detailed performance evaluation includes gain measurements, bandwidth analysis, efficiency assessment, and radiation pattern characterization. Results indicate that while each geometry offers unique advantages, the optimal design depends on balancing multiple performance metrics to meet specific application needs.

The findings provide valuable insights into the potential of novel antenna geometries to push the boundaries of THz technology. This research contributes to the development of advanced antenna designs that can significantly enhance the performance of graphene-based microstrip nanopatch antennas, opening new avenues for high-frequency communication, imaging, and sensing applications. Future work will focus on experimental validation and integration of these designs into practical THz systems.
