Low Loss, Tunable Effective Dielectric Materials

3D Printing for RF & Microwave Devices

Dielectric Materials for RF & MW Applications

Fortify, in collaboration with Rogers Corporation, has developed multiple low-loss dielectric materials for use in high-bandwidth, high-frequency radar and communications systems. The Low Loss 2.8 and Low Loss 4.9 materials consist of a unique low-loss polymer blended with specialty dielectric ceramic additives to create these high-performance dielectric materials.

These game-changing materials are:

  • 10 to 100x less lossy than conventional 3D printed photopolymers with a loss tangent as low as 0.0043 at a 2.8Dk
  • Best in class resolution and surface roughness tailored for wide-band mm-wave applications
  • Able to achieve extreme part complexity & open up design freedom with features as small as 225 microns

Wideband Performance for Next-Gen Radar & Communications

Leveraging unique materials capabilities and design approaches such as lattice-based design, Fortify delivers finished part performance that exceeds any traditional process. For example, functionally graded architectures provide optimal performance for GRIN (gradient index) applications, where we adjust the air-to-dielectric ratio to pinpoint an effective Dk, step multiple effective Dks, or create a continuous gradient of effective Dk between two areas.

Applications for Dielectric Materials Include:

  • GRIN lenses & Wave-guides
  • Connectors
  • Substrates
  • Radomes
  • Conformal Antennas
  • Ultra-low effective Dk Cores
  • Conformal Transmission Lines
  • WAIMs (Wide-Angle Impedance Matching Superstrates)
  • Dielectric Foam
