"millimeter wave 3D-printed antennas match radio frequency performance of those produced using conventional manufacturing... made much cheaper (cost only a few pounds) and faster (in as little as a few hours)... silver nanoparticles, up to 48 GHz... could also be used to produce antennas on a much larger scale and therefore have the capability to cover more areas and bring the fastest mobile networks to parts of the world that have not yet had access"
