Abstract— This paper presents the numerical simulation of the hexagonal-based binary-coding metamaterial antennas in the centimeter-wave band (7-24 GHz) for 6G communication. Two types of unit cells are created by an opposite reflection phase as digital binary “0” and “1” elements. The engineered planar configuration is referred to as a hexagon-based artificial magnetic conductor (AMC) with a vertical stripe pattern. The field source is excited by using an aperture-fed structure with a microstrip line. The advancement of this configuration is that wideband and double band with distinct radiation patterns. The proposed antenna object comes up with a widened impedance bandwidth due to using a hexagonal patch and optimizing the impedance matching of the mutual coupling effect. The full-wave simulation based on the FEM method is used to study the characteristics of antenna performance. The resultant antennas can be operated at the targeted frequency of 79 GHz. The simulated results report the characteristics of scattering and field distribution in terms of reflection, impedance, current configuration, and radiation patterns.
