Over-the-Air Techniques for Measuring Integrated RF Electronics and Antennas

With higher frequencies, the integration of antennas and RF electronics means that many measurements now must be performed over the air. This article addresses the challenges of testing integrated antenna systems in e.g. phased array, antenna-on-chip and antenna-in-package configurations. This article details the latest over-the-air (OTA) measurement techniques for metrics such as noise figure, out-of-band emissions and radiated power spectral density.
