    White paper: Demystifying over-the-air (OTA) testing

    March 31, 2020
    Future technologies and standards will make over-the-air (OTA) testing mandatory. At the same time, integrated antennas are becoming more common with each development cycle such as for low-cost IoT devices and 5G mmWave devices.

    Since measurement requirements will change with OTA testing, engineers need a basic understanding of antennas and antenna measurements. This paper provides you with extensive knowledge on the following:

    • Antennas in general, their parameters and different types, as well as antenna characterization and testing
    • The importance and execution of OTA test setup calibration
    • General concepts that are valid for any OTA test setup, e.g. in-chamber or lab-bench setups
    • Calibration verification
    • Array antenna calibration methodologies
