Planar Near-field Scanner System Error Analysis

摘要

Planar near-field measurement technology is an emerging technology for near-field antenna measurement. It has been widely used in foreign countries. In recent years, domestic develop faster and faster. Gantry motion platform positioning technology is one of planar near field measurement technology key technologies. It has a direct impact on the measurement accuracy. To achieve high-precision planar near field measurement, the most important is high precision scanning system. This paper analyzes the sources of error and error magnitude of planar near-field scanner system.
