Invisible antennas for crowded radio platforms

The possibility to reduce the total scattering by an illuminated object is one of the most intriguing possibilities enabled by electromagnetic metamaterials and metasurfaces. In particular, the impact of cloaking in antenna systems has been found to be remarkable, due to the unprecedented degrees of freedom made available to the antenna designer. In this contribution, we report our latest results on the use of cloaking technology for microwave antennas operating either in the transmitting or in the receiving mode.
