Effect of Number of Probes on Spherical Near-Field Measurement System

摘要

Multi-probe spherical near-field measurement systems offer significant advantages in antenna characterization but are constrained by a fixed number of probes. Determining the optimal probe count for such systems is challenging, as it directly impacts measurement accuracy, system complexity, and cost-effectiveness. This work explores using a robotic arm to replicate a multi-probe spherical near-field measurement system and demonstrates a method for determining the ideal probe count during system design.
