Compact Range Systems

Compact Range Systems
A Compact Range makes direct far-field measurement of electrically large antennas in a shielded anechoic chamber. It uses a large parabolic reflector to project a small radiating source (feed) into the far field. Multiple-feed systems may be used to improve the far-field charac-teristics. The system also allows system level testing of the complete device architecture.
Model Numbers: 
Small, Medium, Large

Main Features

Measurement capabilities

  • Gain and directivity
  • 2-D and 3-D radiation pattern
  • Beamwidth
  • Sidelobe levels
  • Radiation pattern in any polarization (linear or circular) and cross-polarization
  • Radome measurements
  • RCS measurements
  • EIRP and G/T (requires additional RF instrumentation)

Frequency bands

  • Small: 2 - 110 GHz*
  • Medium: 700 MHz - 110 GHz*
  • Large: 700 MHz - 110 GHz*

Quiet Zone Dimension of Reflectors

> Small

  • From 0.3 m Ø to 1.2 m Ø
  • From 1 ft Ø to 4 ft Ø

> Medium

  • From 1.8 m Ø to 3 m Ø
  • From 6 ft Ø to 10 ft Ø

> Large

  • From 3.6 m Ø to 6 m Ø and larger
  • From 12 ft Ø to 20 ft Ø and larger

Max. size of DUT

  • During a full rotation of the DUT, the radiating parts of the DUT must stay within the quiet zone. If accuracy enhancement methods are desired or required, additional space may be needed for the implementation of Antenna Pattern Comparison (APC) and other methods.

Max. weight of DUT

  • 10 to 100 kg for small size system
  • 100 to 1000 kg for medium size system
  • 1000 kg and more for large size system

Typical dynamic range

  • 50 to 80 dB, depending on antenna gain, frequency and RF instrumentation
