downloadpdfFacility Selection

MI Technologies brings state-of-the art processes and systems into its anechoic chambers. This environment contains MI’s industry-leading equipment and instruments. The ranges maintain a trained staff of engineers, technicians and support personnel, familiar with measurement systems, target support systems, model/fixture design and fabrication, and data acquisition/processing systems. 

Our near-field ranges can be configured to conduct planar, spherical or cylindrical measurements and the spherical near-field scanner can also be configured for far-field measurements.

MI’s in-house compact range with an anechoic chamber and a 6 ft cylindrical quiet zone is designed for accurate, indoor antenna, radome and radar cross section (RCS) measurements. It can also be used for free space far-field measurements and includes a full suite of RF and microwave instrumentation and data analysis tools with dedicated radome positioning equipment.

Level of Support

MI Technologies offers broad levels of testing support that can be tailored to your specific needs.

  • Turn-Key: MI Technologies completely defines the test plan, performs the testing and reports findings with analysis as specified by the customer.
  • Time & Materials: The customer provides the test plan and performs on-site direction of the tests, while MI Technologies provides the test range, test system operator and resulting test data.

Testing Volume

Our full-service range can support prototype through full production testing.


Antenna Testing

Whether you need to test in the near-field, far-field or a compact range, MI can provide accurate and fast results.

Radome Testing

We have dedicated radome testing equipment and instrumentation that can be applied to a wide range of requirements, from basic DO-213 testing to custom military requirements that push the limits of today’s measurement techniques.

RCS Testing

We utilize our Compact Range and MI-3048 RCS Analysis Software Option to quickly and accurately process data acquired in an RCS acquisition.


There is no better in the industry to test your antenna designs and ensure they are performing as designed. We can measure:

  • Gain
  • Beamwidth
  • Bandwidth
  • Polarization and Efficiency on Most Yagi, Panel, Patch, Log Periodic, Dipole, Compact Embedded and Conformal and Monopole Antennas
  • Radiation Patterns
  • Axial Ratio
  • Directivity

Characterized and Calibrated

All measuring and test equipment used are traceable to the National Institute for Standards and Technology (NIST). Our calibration laboratory has applied for A2LA Certification through the American Association for Laboratory Accreditation organization and quality system controls are compliant with ISO 9000.
