The scientists of MIPT have developed a 3D printing technique that makes it possible to create complex structures necessary for the production of antennas for 5G and 6G. Experts used affordable 3D printers that work with plastic. In the classic antenna manufacturing technique, more expensive metal-printing devices are used.

The electrical conductivity of polymer antennas is achieved by coating with a metal alloy. According to the developers, the cost of such an antenna is much lower than the cost of a metal printed antenna.

The new method for manufacturing complex antennas consists of five stages: printing a preform using a conductive polymer, surface treatment for improving smoothness, placing auxiliary electrodes on the preform, electroplating, removing the preform.
