Inkjet printing of UHF antennas on corrugated cardboards

Researchers at the Technische Universität Chemnitz in Germany established a method based on inkjet printing to develop UHF antennas on a corrugated cardboard for packaging applications.
The researchers found that they could obtain well-defined silver layers on the cardboard substrates due to a primer layer approach. The primer layer is based on a UV-curable ink formulation and deposited as well as the silver ink with inkjet printing technology. The primer layer was proven to optimize the surface characteristics of the substrate, mainly reducing the surface roughness and water absorptiveness. An article about the research is published in Applied Surface Science.
