DIATOOL
Perform antenna diagnostics, reconstruct near-field and surface currents of the antenna under test (AUT) from measured radiated fields and filter undesired radiation.
Features
- Reconstruct the extreme near field with a resolution better than half a wavelength
- Planar reconstruction for fast analysis of large antennas; inverse MoM for higher resolution
- Definition of the AUT geometry by CAD or mesh file import
- Automatic generation of reconstruction surface through best-fit canonical surfaces, CAD or mesh files
- Visualisation of reconstructed currents over AUT surface
- Compatible with most near-field and far-field range data formats
Values
- Early detection and location of antenna anomalies
- Remove noise from measurements by filtering
- User friendly interface
3D current reconstruction technique
The 3D reconstruction technique uses higher-order basis functions and curved quadrilateral patches. It makes it possible to reconstruct field and surface currents on arbitrary surfaces enclosing the AUT, including conformal surfaces when necessary, with a spatial resolution which can be better than half a wavelength.
- Input measured field (in amplitude and phase) on any acquisition surface, incl. truncated and irregular surfaces
- Field reconstruction on arbitrary surfaces enclosing the AUT and conformal to it
- Applicable to electrically small and medium sized antennas
- Effective memory use
Planar reconstruction
The planar reconstruction technique involves a spherical-wave to plane-wave transformation. The field is reconstructed on planar surfaces in front of or around the AUT, with a spatial resolution which can be better than half a wavelength.
- Input measured field (in amplitude and phase) on a full sphere
- Field reconstruction on a plane or combination of planes
- Applicable to both electrically small and large antennas
- Extremely fast computation with low memory requirements
Filtering of undesired radiation
Efficient post-processing of measured fields by computation of clean antenna patterns where reconstructed currents on cables, mounting fixture or selected areas of the reconstruction surface are suppressed.
Enhancement of measured patterns
Compute noise-free patterns radiated by the reconstructed currents – the conformal reconstruction surface acts as a physics-based filter that includes the shape of the AUT.
