Since the past decade phased-array antennas can no longer be ignored in the commercial market. This market reaches from telecommunication to automotive and beyond. Presently, antenna-in-module and antenna-in-package (AiP and AiM) are the most common formfactors. But as the carrier frequency (THz) and modulation bandwidths (multiple GHz) are increasing, antenna-on-chip (AoC) will play an important role, eliminating completely the traditional separation between conductive and antenna design and test. Consequently, system level designers and characterization engineers need to deal properly with conductive, antenna and radiating aspects. System level simulators evolved already including radiation aspects but it is a long way before extracting decent behavioral models that can deal with the vast number of parameters. Anechoic chambers in different sizes are commercially available but are cumbersome, time- and space-consuming for the engineer accustomed to conductive testing. Would it thinkable to come up with a desktop version as a natural extension to a cable, connecting instruments? This session introduces to industrial characterization engineers and system level designers of phased-array antenna systems the newest developments related to fast and compact characterization, even useable for production test and their impact on the improvement of system level simulation.
