OTA Antenna Test System for 5G and mmWave Frequencies

A new turnkey solution for customers needing to make far-field antenna measurements above 18 GHz. The over-the-air (OTA) antenna measurement chamber solution features a wide array of configurations depending on the user’s anechoic chamber requirements, antenna size, desired frequency range, and antenna positioner functionality.

CMT has partnered with MilliBox and Eravant to offer a complete OTA antenna measurement chamber solution for engineers needing to make measurements from 18 GHz to 220 GHz. Each OTA bundle can be configured with a set of 2,3, or 4 anechoic chamber cubes, depending on far field measurement requirements.

The measurement system is anchored by CMT’s 2-port 9 GHz Cobalt VNA and includes a 3D antenna positioner (Gimbal), sophisticated but intuitive measurement software, frequency extender modules, and other necessary accessories to fully set up a chamber for far field antenna measurements.

These comprehensive OTA solution bundles provide a low-cost, space-saving solution that is ideal for antenna testing applications across automotive radar, aerospace, satellite communication, and similar industries.

The OTA bundle is an all-in-one solution that provides everything needed to accurately test a large number of antennas. The combination of affordability and portability will enable multiple systems in a single lab environment for users to simultaneously test multiple antennas.
