Electronically Steered Array (ESA) antennas are regarded as a pivotal technology for satellite terminals in emerging constellations and the integration of Non-Terrestrial Networks (NTN) with terrestrial communication systems. Their advantages include beamforming and beam steering capabilities, which enable seamless handovers between fast-moving satellites, as well as support for multiple beams, facilitating multi-orbit operations. This presentation explores the latest advancements in phased array antenna technologies and proposes test solutions for verifying their critical performance parameters.
