The growing demand for wireless communication systems has increased the need for smaller, high-performance antennas capable of delivering fast data rates, broad coverage, strong gain, and wideband operation. Microstrip patch antennas (MPAs), especially when combined with metamaterials (MTMs), are an excellent solution to fulfill these requirements. This research addresses the knowledge gap in the coordinated use of MTMs with hexagonal arrays of MPAs in the terahertz frequency band for 6G applications. The primary objective is to design and analyze a novel hexagon-shaped metamaterial structure-based antenna to enhance MPA performance. Using the high-frequency structural simulator (HFSS) software, the design, simulation, and measurement of the metamaterial-based hexagonal MPA were conducted. This innovative hexagonal metamaterial unit cell, measuring 2.5 × 2.5 mm2, is distinctive in its design. The proposed antenna, with overall dimensions of 36 × 40 × 1.6 mm3, was simulated on a 1.6 mm thick FR-4 substrate at an operating frequency of 0.1 THz. Results indicate that the proposed antenna achieves a gain of 7.137 dB and a radiation efficiency of 99.96%. These features make the proposed antenna highly suitable for 6G applications and advanced wireless communication systems.

摘要

The growing demand for wireless communication systems has increased the need for smaller, high-performance antennas capable of delivering fast data rates, broad coverage, strong gain, and wideband operation. Microstrip patch antennas (MPAs), especially when combined with metamaterials (MTMs), are an excellent solution to fulfill these requirements. This research addresses the knowledge gap in the coordinated use of MTMs with hexagonal arrays of MPAs in the terahertz frequency band for 6G applications. The primary objective is to design and analyze a novel hexagon-shaped metamaterial structure-based antenna to enhance MPA performance. Using the high-frequency structural simulator (HFSS) software, the design, simulation, and measurement of the metamaterial-based hexagonal MPA were conducted. This innovative hexagonal metamaterial unit cell, measuring 2.5 × 2.5 mm2, is distinctive in its design. The proposed antenna, with overall dimensions of 36 × 40 × 1.6 mm3, was simulated on a 1.6 mm thick FR-4 substrate at an operating frequency of 0.1 THz. Results indicate that the proposed antenna achieves a gain of 7.137 dB and a radiation efficiency of 99.96%. These features make the proposed antenna highly suitable for 6G applications and advanced wireless communication systems.
