Do anyone noticed the new technology of gap waveguide? I don't expect metamaterial go that far. It seems this type of waveguide is suitable for integration of MMICs and antenna above 30Ghz.
But I don't see any large antenna array realized in this technology. It mostly appeared in Gothenburg's university paper.
