Antenna Test Chambers

Positioners, controllers and software were developed for the antenna measuring chambers themselves. Customers include well-known universities, research institutes and customers from the telecommunications, aviation and defense industries. The absorbers for the chambers come from the market leader Emerson & Cuming. 

Compact Antenna Test Ranges

• Antenna reflectors for Compact Ranges have been realized for frequencies between 600 MHz and 300 GHz.
• Quiet zones up to 6 m diameter
• Reflectors are made of massive Aluminium
• Surface accuracy better than 15 µm (peak-to-peak)
• Data sheet serrated single reflectors for Compact Antenna Test Ranges

Near-Field Measuring Systems

Planar, cylindrical and spherical near-field measurement systems have been realized by Asysol for frequencies from 300 MHz to 110 GHz (certified by ESA).

Planar and Cylindrical Near-Field Antenna Test Systems

• Scan range up to 40 m x 20 m
• Scan speed up to 400 mm/s in X- and 700 mm/s in Y-direction
• High planarity of 0.06 mm
• Absolute encoders for highest accuracy
• Simultaneous measurement of both polarisations
• Data sheet planar near-field measuring systems

Spherical Near-Field Measuring Systems (Phi über Theta)

• Antenna loads up to 1500 kg
• Rotational speed up to 3 rpm (azimuth) and 5 rpm (roll axis)
• Repeatability better than 0.01°
• Simultaneous measurement of both polarisations
• Data sheet spherical near-field measuring systems

Spherical Near-Field Measuring Systems (Gantry over Azimuth)

• Antenna loads up to several tons (cars, trucks, airplanes)
• Rotational speed up to 3 rpm (azimuth) and 5 rpm (roll axis)
• Angular accuracy better than 0.01°
• Gantry radius 0.5 m to 15 m
• Radius accuracy better than 0.05 mm
• Simultaneous measurement of both polarisations
• Data sheet spherical near-field measuring systems (gantry over azimuth)

Hybrid Antenna Measurement Systems

Asysol has many years of experience in combining compact ranges and near-field or far-field antenna measurement systems. The cover of the CATR reflector with absorbers is automatically and motorized. The combination of two measuring methods in one system improves the flexibility and the measuring possibilities while at the same time offering low costs and requiring little space.

Antenna Positioners

Positioners for antenna measurements are available from Asysol for different antenna weights (chip antennas, base station antennas, vehicles and aircraft) and degrees of freedom.

• Calibration of the positioner under load conditions
• Accuracy better than 0.01°
• Backlash-free operation
  
• Integrated sliprings and rotary joints
• Data sheet azimuth positioners

Horn Antennas and Probes

• Standard Gain Horn Antennas
• Antenna measurement probes
• Frequencies from 500 MHz to 300 GHz.
  
• Data sheet rectangular waveguide probes
• Datasheet corrugated antenna feeds
  

Software for Antenna Test Systems

ASYSOL has developped a modular software for

• Acquisition of antenna measurement data
• Mesurement analysis
• Transformation of near-field measurements to far-field (with TICRA)
• Visualisation of measurement results (2D and 3D Plots)
• Antenna measurement software brochure ASYSOFT
