Po raz pierwszy wydrukowano anteną 3D z podwojnym reflektorem na pasmo 14.5GHz
kolejna drukowana antena:

3-D Printed Horn Antennas

3-D printing allows the specifications in software of arbitrary shapes and
complex curves for horn antennas, then printing and applying a conductive
coating. This allows expermentation with almost any shape — and raises
interesting intellectual property issues.
