Surface roughness simulations for 6G additive antennas

Additive technologies show promising results in 6G antennas operating in W-band. However, quality of additive manufacturing strongly depends on many crucial factors related to the manufacturing process. In this work we perform electromagnetic simulations to study an impact of surface roughness to the performance of some conventional antennas suitable for 6G applications. Finally, we could define the surface roughness requirements for the additive antennas.
