Antenna Measurement Ranges – Planar/Spherical Near-Field & Far-Field | Asysol

ASYSOL delivers turnkey near- and far-field ranges, covering planar and spherical near-field as well as Far-Field/SNF configurations for large AUTs. References include more than 20 spherical NF installations and planar scanners with outstanding flatness and positioning accuracy.

Benefits

• Top-tier geometric accuracy: planarity 0.15 mm uncorrected, <0.06 mm corrected.
• Large scan areas: up to 40.0 m × 17.2 m for planar NF.
• Heavy AUT capability: spherical NF with antenna load up to 1500 kg; position repeatability 0.02°; rotation >5 rpm.
• Simultaneous dual-pol acquisition in NF systems.
• Local support by EMCO Elektronik for consulting, integration and service in D-A-CH.

Main Features

• Planar NF: inverted “T” frame, X up to 400 mm/s, Y up to 700 mm/s; tower designed to minimize scattering.
• Spherical NF: lower frequency starting at <200 MHz, simultaneous dual-pol.
• Far-Field/SNF ranges with roll/azimuth and gantry mechanics.
• Turnkey layouts incl. shielding/absorbers with leading partners.

Typical Applications

• Characterization of communication, radar and satellite antennas (aerospace, defense, automotive, academia).
• OTA measurements of large AUTs and accurate pattern reconstruction.
• Validation of active/passive RF devices in lab and production.

Additional Information

ASYSOL provides tailored mechanics (multi-axis AUT positioners, guaranteed orthogonality 0.02°, axes intersection ≤0.05 mm) and project-specific kinematics. Combined with ASYSOFT and third-party software, this yields robust, scalable measurement chains.
