Eravant, the leader in mmWave and sub-THz components, and MilliBox, the leader in compact benchtop mmWave anechoic chambers, have partnered to launch two new Compact Antenna Test Range (CATR) products.
CATR is a type of over-the-air (OTA) antenna test system which uses a parabolic reflector to eliminate the far field measurement distance requirement. When the frequency increases, the far-field distance also increases and direct far-field measurements, 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.
Eravant has launched a new product line of Open Bed Compact Range systems. The STY-CATR-0150-OB-S1 product is a benchtop 3D antenna testing setup that is capable of testing from 24 GHz to 170 GHz with a 150 mm quiet zone. This model integrates the MilliBox GIM04-300E 3D positioner and its complete data acquisition software. This product line is marketed by Eravant.
MilliBox has developed the new MBX32CTR as 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.
In this CATR setup, 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 provides frequency extenders for spectrum usage above 50 GHz. This full package is available in the market as a complete solution by MilliBox.
“While working together for years, we soon realized that by combining our strengths we could offer unique solutions to the OTA testing market” says Wendy Shu CEO of Eravant. “MilliBox has chambers, 3D positioners and software, while Eravant has frequency extenders and precision CNC fabrication expertise, it made so much sense to combine those for the market benefit”
During the IMS 2024 exhibition, MilliBox will be showing the MBX32CTR-06 in 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. Eravant will demonstrate its new Open Bed Compact Range product at booth 1939 with live data captured at 140 GHz.
