High-gain Artificial Magnetic Conductor Integrated Antenna for 5G Communication Systems

This article introduces a novel meta-surface configuration designed to enhance the gain of antennas for advanced communication systems. The proposed design features a rectangular meta-surface with circular cutouts placed beneath the rectangular ring, which contributes to improved electromagnetic performance. The core of the system is a rectangular monopole antenna, carefully designed to operate at two frequency bands: 3 GHz and 8 GHz. These dual-band capabilities ensure the antenna's adaptability to various wireless communication needs. To further boost performance, the monopole antenna is supported by two Artificial Magnetic Conductor (AMC) structures, which resonate at 3.9 GHz and 8.8 GHz, respectively. These AMC layers improve signal stability and improve the overall efficiency of the antenna. The antenna achieves a bandwidth of 3.2 at the 0.9 GHz resonance and 0.829 at the 3.9 GHz resonance, demonstrating its ability to maintain wide and stable operational ranges. Furthermore, when the design incorporates a 4×4 AMC array, the antenna's gain reaches 8.23 dB, ensuring stronger signal strength and improved coverage. This combination of meta-surface, monopole, and AMC structures provides a compact, efficient, and high-performance antenna suitable for real-world applications. With its improved gain, wide bandwidth, and reliable performance, this antenna design is a highly promising solution for enabling seamless 5G communication networks. It offers a powerful and efficient option for next-generation wireless systems that require enhanced signal integrity and broader coverage.
