Near-Field Measurement System～Cylindrical ～

Mobile devices are operated on higher frequency band, especially mm-waverecently. The measurement environment for higher frequency and bigger size DUT demands the space(to secure the enough distance between DUT and measurement antennas) for the accuracy measurement. Our Near-Field measurement system, which is compact solution, make you to measure the accurate electric-field of DUT near-field.
Our MATEOS software can convert its measurement date to far-field data.
Enable to install this into existing chamber room due to compact size.

＊Customize available for size and specifications.
The above may change without advance notice.

Conversion from Near Field to Far Field

This is result sample of Electromagnetic Simulation and conversion from NF to FF under CNF(CylindricalNearFar). Those response are almost matched into graph in below.

Passive Conversion from Near Field to Far Field DUT Network

The result of conversion antenna NF measurement by VNA to FF.

Conversion Near Field to Far Field (Active for 5G)

This is Near Field conversion to support the active measurement of the call connection between 5G device and Base station simulator. Enable to measure NF amplitude and relative phase distribution of DUT by using Phase Reference & Rx antennas, which data makes to support the NF-FF conversion.

3-Coordinates

Enable to NF conversion for all of Planar, Cylindrical and Spherical coordinates near field measurement systems.

This NF measurement system demands AZ positioner and Antenna tower with suitable DUT size into chamber room. MWF can support the several types of positioners and towers as customer request.
