DIATOOL
Perform antenna diagnostics, reconstruct near-field and surface currents of the antenna under test (AUT) from measured radiated fields and filter undesired radiation.
For Advanced Near-field Test Ranges
Assisting test-range staff and antenna designers in identifying the origin of possible discrepancies in the designed and measured far-field patterns, DIATOOL works with the measured complex data (amplitude and phase) to view currents on the antenna under test (AUT) or on a surface enclosing the antenna.
Why DIATOOL
Helping engineers accurately reconstruct extreme near field and surface currents.
Extreme field reconstruction
Reconstruct the extreme near field with a resolution better than half a wavelength
AUT geometry definition
Define the AUT geometry by CAD or mesh file import
Compatible with most data formats
Compatible with most near-field and far-field range data formats
Reconstructed current visualisation
Visualise reconstructed currents over AUT surface
Automatic reconstruction generation
Generate reconstruction surfaces automatically through best-fit canonical surfaces, CAD or mesh files
Planar reconstruction
For fast analysis of large antennas; inverse MoM for higher resolution
Key product highlights
- Early detection and location of antenna anomalies
- Remove noise from measurements by filtering
- User friendly interface
Core capabilities
Everything you need – in one environment.
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
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.
