Method for rapid prototyping radio frequency microwave devices

Value Proposition

Traditional waveguides are composed of pure metals, which are pricey and heavy. Low-cost and low-cost waveguide and antennas are thus much desired, especially for mobile and aerospace applications.

Technology

Inventors at Duke developed a method for rapid manufacturing of waveguide components. Low-cost precision waveguide components can be fabricated by using high precision three-dimensional printing and plated with copper using both electroless plating and electroplating. The printed pyramidal antenna performed as well as industry-made antenna in near-field scanning.

Advantages

  • Reduced cost and fabrication time
  • Produces lightweight devices that can be customized for specific applications
  • Performance is comparable with standard waveguides
