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
