The radiative antenna is optimized in terms of size and dielectric properties of the substrate. The role of surface waves is studied as a function of the thickness of the dielectric substrate and the relative electrical permittivity. As a result, optimal in-coupling of RF signal is strongly determined by the surface waves.
