Emerson & Cuming offers a variety of material solutions to address stray free-space and cavity-resonance radiation problems encountered by automotive radar module designers and manufacturers.

Absorber solutions include:

  • VSWR suppressant
  • Side lobe attenuation
  • Radome refraction mitigation (sharp radome corners can refract light nonlinearly)
  • Surface reflectivity absorber (cavity resonance and propagating wave)
  • Feedline termination

Low loss dielectric solutions include:

  • Ultra low loss radomes
  • Molded antenna spacing material (patch, phased array, etc.)
  • Custom lenses (Fresnel, Lunenberg, etc.)
  • MMIC chipset caps
