SOLUTION FOR
• Planar near-field measurement
• Calibration and polarization reference

  • Technical Performance
    • Dual linear polarization with high polarization purity and isolation
    • Mono-mode excitation on a 3:1 bandwidth
    • No sidelobes and no pattern nulls in the forward hemisphere
    • Low interaction between probe and the antenna under test
  • Design
    • Wideband orthomode junction (OMJ) based on inverted quad-ridge circular waveguide with external feeding circuits, feeding a circular aperture
    • Easily interchangeable apertures with tapered ends to minimize diffraction effects
  • Surface treatment
    • Alodine 1200 according to MIL-C 5541E class 3
    • Polyurethane paint
  • Repeatability
    • Repeatable radiation performance due to the axial symmetry of the interchangeable apertures
