INDIANAPOLIS, IN, September 6, 2024 — The OTA antenna test system is a turnkey solution for customers needing to make far-field, mmWave and sub-THz antenna measurements above 18 GHz. CMT has partnered with MilliBox and Eravant to offer this complete over-the-air (OTA) antenna measurement chamber solution for measurements up to 220 GHz. All three partner companies will be co-located at Stand 403M during European Microwave Week 2024 in Paris. 

“With their simplicity and performance, these one-stop-shopping combinations are very compelling propositions for the ever-growing global market for mmWave and Sub-THz antenna testing,” explains Jeanmarc Laurent, the creator of MilliBox. “Traditional anechoic chambers are often room sized, painful to share, and very expensive to own. Instead, these bundles allow users to test phased-array antennas with a flexible and accessible measurement system at a fraction of the cost of similar offerings.” 

The OTA Antenna Test System features a wide array of configurations depending on the user’s far-field requirements, antenna size, desired frequency range, and antenna positioner functionality. Each OTA system includes a benchtop compact anechoic chamber, a 3D antenna positioner (gimbal), sophisticated but intuitive measurement software, and other necessary accessories to fully set up a chamber for far-field antenna measurements. Each system is anchored by CMT’s 2-port 9 GHz Cobalt VNA and includes a set of frequency extenders for the measurement band of your choice.  

These comprehensive OTA solution bundles provide a low-cost, portable, space-saving solution that is ideal for 5G and mmWave and sub-THz antenna testing applications across automotive radar, aerospace, satellite communication, and similar industries. “We wanted to develop an over-the-air antenna measurement solution that’s accessible to an assortment of radar engineers, antenna designers, etc.,” says Brian Walker, Senior RF Design Engineer SME. “The OTA bundle is an all-in-one solution that provides everything needed to accurately test small mmWave antennas. The combination of affordability and portability will enable multiple systems in a single lab environment for users to simultaneously test multiple antennas.”
