Spherical near-field measurement systems acquire antenna radiation data in amplitude and phase on a spherical surface surrounding the antenna under test.

High measurement accuracy in confined spaces and applicability to antennas of any size and complexity make it ideal for production validation in compact facilities.

Near-field transformation applies advanced mathematical algorithms based on spherical-wave theory to convert measured near-field data into far-field radiation patterns. Probe characteristics and measurement uncertainties are accounted for during the process to deliver accurate results.

Yes. Source reconstruction techniques compute equivalent currents and fields in the extreme near-field region of the antenna to pinpoint fabrication issues, surface distortions and misalignments.

Detailed diagnostics reveal exactly where problems originate and how they affect performance.

Probe correction accounts for the full electromagnetic characteristics of measurement probes, including radiation pattern and impedance mismatch effects. Advanced algorithms apply precise corrections during far-field transformation, eliminating measurement distortions and improving overall accuracy.

The probe correction in SNIFT fully compensates for the impact of rotationally symmetric probes excited by the fundamental TE11 cylindrical waveguide mode

Processing speed depends on dataset size, antenna complexity and frequency, but TICRA’s near-field transformation software processes typical spherical measurements in seconds. Rapid turnaround accelerates production validation cycles and reduces time-to-market for antenna systems.

Yes. The DIATOOL software supports standard reconstruction surface shapes and user-defined geometries represented by CAD files.

Flexibility in surface definition allows diagnostics tailored to your specific antenna design and measurement configuration.

Near-field validation bridges design simulation and field performance by providing rigorous experimental verification at critical production milestones. Early detection of issues through measurement diagnostics prevents costly rework and ensures antennas meet performance requirements before deployment.
