• Models up to 500 GHz
  • Low End Diffraction


  • Planar & Cylindrical Near Field Measurements
  • Calibration

Flann offer a complete range of small aperture open-ended near field waveguide probes designed specifically for planar and cylindrical near field measurements and calibration.

The end diffraction is minimised by utilising a 10° chamfer to give a knife edge aperture of less than 0.5 mm.

Standard probe lengths include 100 mm, 200 mm & 300 mm.

Custom lengths and flanges are available on request.

Typical Performance

  • VSWR better than 2.5:1
  • Gain 5.5 dB
  • Gain variation ± 2 dB
