Abstract: The proposed work presents the design and performance analysis of a high-gain Artificial Magnetic Conductor (AMC) integrated antenna intended for millimetre-wave 5G communication applications. The study evaluates different AMC unit cell configurations and their impact on reflection characteristics and radiation performance. The reflection coefficient (S11) analysis of three AMC designs, namely AMC 0, AMC 1, and AMC 2, reveals distinct electromagnetic behaviors. Among them, AMC 1 exhibits a sharp resonance around 28 GHz, indicating strong frequency selectivity and effective AMC operation, while AMC 0 demonstrates a broader response with moderate bandwidth characteristics. AMC 2, in contrast, shows minimal variation and lacks a significant resonant response, indicating poor AMC performance. These results highlight the critical role of unit cell geometry and spacing in determining the reflection properties and operational efficiency of AMC structures. The optimized AMC configuration is further arranged in a periodic array, enhancing the antenna’s overall radiation characteristics. The gain distribution and 3D radiation pattern demonstrate a peak gain of approximately 5.53 dB, with a stable and directional radiation profile. The radiation pattern exhibits a broad main lobe with acceptable side lobe levels, confirming improved directivity and efficient energy radiation. The color-coded gain plot further illustrates uniform gain distribution across the radiating surface, validating the effectiveness of the AMC integration in suppressing surface waves and enhancing forward radiation. Overall, the integration of the optimized AMC array with the antenna significantly improves impedance matching, gain, and radiation efficiency. The proposed design demonstrates suitability for 5G millimetre-wave applications, particularly around the 28 GHz band, by achieving a balance between bandwidth, gain, and structural simplicity. The results confirm that AMC-based antenna designs offer a promising approach for next-generation high-frequency wireless communication systems.
