MilliBox Unveils Compact Antenna Test Range for 3D OTA Measurements in Sub-THz Spectrum

MilliBox, a leading developer of compact benchtop mmWave anechoic chambers and antenna positioners, has introduced a full Compact Antenna Test Range (CATR) capable of 3D radiation pattern in sub-THz spectrum. CATR is a type of over-the-air (OTA) antenna test system that uses a parabolic reflector to eliminate the far-field measurement distance requirement. When frequency increases, the far-field distance also increases and direct far-field measurements, as used in other MilliBox, may become impractical for large antenna array applications. In this situation, the use of a parabolic reflector and a precisely placed probe render the test system compact and practical as a benchtop setup.

The MBX32CTR is a complete solution for mmWave and sub-THz OTA measurement with a quiet zone of 150 mm. This package includes an MBX32 chamber, GIM04H-300E 2-axis positioner, laser alignment system, 300 mm parabolic reflector, and its focus probe antenna.

This product comes from the cooperation between MilliBox and Eravant. MilliBox contributes the chamber and the 3D antenna positioner, while Eravant developed the 300 mm reflector and probes for the frequency band required. Eravant also contributes frequency extenders for spectrum usage above 50 GHz. Maury Microwave provides the StabilityPlus Low Profile cable assemblies needed to carry the signals out of the 3D positioner. This full package is introduced on the market as a complete solution by MilliBox.

“Through internal innovation or with strategic partnerships, MilliBox continues to pave the way for accessible test systems that makes mmWave and sub-THz possible for all,” says Chinh Doan, CEO of MilliBox.

During the IMS 2024 exhibition, MillBox is showing the MBX32CTR-06 at their booth 705 for the first time. This demonstration operates in D-Band 110 GHz to 170 GHz and performs a live display of 3D antenna radiation pattern captured in real time.
