printed antenna
Printed antennas offer advantages wherever space is extremely limited, such as in RFID cards, smart wearables or other radio-based miniature systems.
Printed antennas have the advantages that they can be printed very inexpensively by printing machines using letterpress, screen printing or gravure, or by inkjet prin ters, and are only a few micrometers thick.
The flat antennas are printed with a conductive ink such as silver ink on flat, curved or curved surfaces. The nozzle diameter of the spray nozzles meets the requirements for ultra-fine structures of around 100 nm.
