How to Design and 3D Print a Radar Target Using Low-Loss Gradient Dielectrics

3D-printed microwave lenses are a commercially viable option for RF devices deployed in the field. When a mission-specific radar target signature is required quickly, a Luneburg-style lens can be configured as a wideband retroreflector to tailor the signal received by threat radars.

You'll learn how engineers at CTI, an HII company, used Ansys HFSS and Fortify's 3D printing technology combined with Rogers Corporation's new Radix low-loss printable dielectric to design and print efficient gradient-index lenses for a drone-mounted radar target application. These presenters will illustrate the workflow from design concept to printed results and correlate simulation results with test data.

What Attendees Will Learn

Join us on 5th April, 11 a.m. ET to design and simulate 3D print Luneburg-style lenses for drone-mounted radar targets.

  • How CTI is leveraging groundbreaking simulation and manufacturing technology to innovate in the Defense and Intelligence Sectors
  • How CTI designs quick-turn mission-specific RF devices with spatially varying properties using Ansys HFSS
  • See the complete design and manufacturing workflow from RF device concept to 3D printed part
  • Specifics about Fortify's unique 3D printing technology and geometry solutions used for creating artificial dielectric media
  • Learn the benefits of utilizing 3D-printed GRIN (Gradient Refractive Index) components for RF devices
