Simulation of the microwave five-band a perfect metamaterial absorber for the 5G communication‏

This study proposes a five-band perfect metamaterials absorber (MMA) for 5G communication in the K- and Ka-bands of the microwave range. The MMA design is based on a folded arms resonator (FAR) with a novel shape, forming the fundamental unit of the absorber. This absorber demonstrates a reasonably...

description This study proposes a five-band perfect metamaterials absorber (MMA) for 5G communication in the K- and Ka-bands of the microwave range. The MMA design is based on a folded arms resonator (FAR) with a novel shape, forming the fundamental unit of the absorber. This absorber demonstrates a reasonably wide range of absorption capabilities for 5G communication in the K and Ka bands of the microwave region. The absorptivity of the MMA was examined for both normal and oblique incidence of waves in the frequency range of 20–26 GHz. According to a theoretical analysis, five absorption peaks at resonance frequencies of 20.38, 21.75, 23.1, 24.22 and 25.12 GHz exhibit absorption rates of 97.8%, 92.9%, 97.2%, 99.3% and 96.8%, respectively. The overall average absorption rate is 95.53%, taking into account the presence of two perfect absorption peaks. By adjusting the structural parameters, it is possible to influence the absorption peaks and resonant wavelengths. Additionally, the absorber demonstrates a high level of symmetry, resulting in insensitivity to TE mode polarisation angle and incident angle. The fractal resonators exhibited a capacitive effect at lower frequencies, while the SRRs demonstrated a capacitive effect at higher frequencies. This MMA design is expected to have practical applications in 5G communication technology.
