Resumen

A reflectarray antenna at 28 GHz is proposed tobe used as a base station in 5-G indoor communications. Thereflectarray is integrated in an office and the near-field radiatedover a desktop surface is simulated. Since the near-field is notproperly focused on the area defined for 5-G coverage, anoptimization of the reflectarray is required. The generalizedIntersection Approach algorithm is employed to optimize theradiated field at the plane of the desktop surface in order toimprove the coverage area. Then, a comparison between thenear-field before and after the optimization is carried out,showing a significant improvement of the coverage area. Inaddition, other planes are analyzed, allowing to extend theresults from the optimized plane to others.
