Demystifying Over-The-Air (OTA) Testing – Important Antenna Parameters, Test System Setup, And Calibration

Whether in low-cost devices targeting the IoT market, highly integrated radio frontends for satellite communications links, or mm-wave devices, integrated antennas are becoming more common with each development cycle. Therefore, OTA testing is becoming more important (or even mandatory) for broader audiences. The step from conducted measurements to OTA testing changes the measurement requirements to a certain degree, so users must have a basic understanding of antennas and antenna measurements. This paper will introduce antennas, antenna characterization and testing, as well as discuss the importance and execution of OTA test setup calibration. Download the full paper for more information.
