Abstract
Metasurface antennas are thin two dimensional metamaterial layers that allow or inhibit the propagation of electromagnetic waves in desired directions in free space or antenna surface. In literature they have been demonstrated to guide and make surface waves radiate to obtain a specific desired radiation pattern. Their low cost, easy integration and low losses make them promising candidates for implementing solutions of next generation receivers and transmitters for high speed wireless telecommunications, in particular for 5G and beyond-5G standards. These antennas are planar structures made up by sub wavelength periodic conductive elements, printed on a grounded dielectric substrate. By changing the individual elements shape it is possible to obtain a given current distribution, thereby design a suitable radiation pattern.
However, the analysis and design of such structures is particularly challenging because of the multi-scale features that characterize the patterned surface: electromagnetic behavior is usually described macroscopically by a simplified model with the Impedance Boundary Conditions (IBC)
