Current manufacturing process limits the supplies available and can be wasteful

Current methods for making mm-Wave passive components and antennae are expensive, time-consuming, require a cleanroom, and result in chemical waste. Furthermore, the nature of the manufacturing process means that paper and low melting-point plastics cannot be used.

Innovation allows for massively scalable passive components for inkjet printing

Georgia Tech researchers have found a way to create massively scalable 2D and 3D antennas and passive components using inkjet printing. This method allows components to be created in minutes, without a cleanroom, and at much lower cost on rigid and flexible substrates. The equipment is flexible and portable, meaning it can be bought to remote locations in order to modify or create components as needed.

This invention uses inkjet printing fabrication techniques in order to create 2D and 3D antennas and passive components. No other inkjet process is capable of creating multi-layer components that operate up to mm-wave, 5G+ or tens of GHz / sub-THz frequencies.

Solution Advantages
  • Rapid fabrication at low cost on any substrate, which is not possible with current techniques
  • Flexibility and portability; required equipment is small and does not need a cleanroom
  • No other inkjet process has created multi-layer printed components that operate up to mm-Wave or GHz
  • On-demand customization with minimal additional fabrication/cost overhead
Potential Commercial Applications
  • Printed RF capacitors and inductors
  • mm-Wave antennas and antenna arrays
  • Can be extended to inkjet-printed chemiresistive/capacitometric sensors, integrated long-range RF/mmW/5G+/sub-THz modules, and super-capacitors for energy storage
  • Can cover IoT, 5G+, RFID, precise agriculture, smart cities, smart wearables, smart skins and Industry 4.0 applications
