Metasurface antennas beyond 41 dBi of directivity

Our latest prototype for ground-to-satellite communication showed a measured directivity of 41.2 dBi in the Ka band (30 GHz). Beside that, its pattern satisfies the mask requirements defined by the service provider. The antenna has a diameter of 50 cm and a thickness of just less than 10 mm, including the support.
