As it does so, a 3D printer system prints a rigid back structure to the blanket array membrane. As it does so, the hard UV radiation of space rapidly cures the resin, making it hard. This means a ...

Abstract: In this paper, a 3D-printed dual-band reflect-transmit-array (RTA) antenna has been presented, which operates as a reflectarray (RA) in the 28 GHz band and as a transmitarray (TA) in the ...

As the saying goes — when life gives you lemons, you make lemonade. When life gives you a two-ton surplus industrial robot ...

A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...

Abstract: Massive MIMO technology has significantly enhanced the performance of 5G networks, and its potential is poised for further expansion in the upcoming 6G standard. Large antenna arrays at the ...
