Phased-array antennas, also called Electronically Steered Array (ESA) antennas are a key enabler for next-generation satellite user terminals, especially as emerging satellite constellations and Non-Terrestrial Networks (NTN) become integrated with terrestrial communication systems. These constellations require phased-array antenna technology that can be produced and deployed on a large scale, which aligns with the efficiencies seen in the telecommunications mass market, but is still relatively new to satellite communications. Fast and efficient antenna performance verification is essential throughout the entire product lifecycle to meet this demand. This includes the research and development phase as well as high-volume production testing and in-operation diagnostics. This presentation introduces streamlined measurement and verification methods designed to support the rapid scaling of phaed-array antenna technology. These techniques enable comprehensive performance validation, such as calibration verification, radiation pattern analysis, efficient multi-beam testing, and link reliability, while reducing time and cost. The focus is on practical implementation for scalable production and reliable field operation to support consumer- and enterprise-grade satellite communications.
