3D Printed Antennas and RFID for Greater Design Freedom and Improved Performance

3D Printed Circuit Board (PCB) for Rapid PrototypingThe DragonFly™ 2020 Pro 3D Printer makes it possible to 3D print antennas, arrays and Radio Frequency Identification (RFID) tags using conductive nanoparticle silver and dielectric inks. This innovation enables antennas to play a role in more products and for antennas to be placed in new locations. The Internet of Things (IoT) and other connected technology applications, such as the adding of antennas to packaging or flexible antennas and RFID tags are just a few examples of the march of connectivity and thus antennas into more and more locations The ability to 3D print fine-featured circuitry with complex geometries and built-in antennas results from an additive manufacturing technology able to produce a better performing product with reduced product size and weight.

The precise 3D manufacturing process accurately controls the location and thickness of the deposited material, ensuring the end-product antenna can offer optimal reception and transmission. This enables new possibilities for freeform designs which can lead to reduced antenna size, improved performance, efficiency all whilst benefitting from much shorter product development lead-times.. Antenna prototypes can be printed in hours, with no need for screens or setup, enabling the optimization of designs through rapid in-house testing and iteration. Inkjet-printed Nano silver has also shown to significantly improve antenna performance over copper.
