Development of the 3D RFID static test system in a spherical near-field antenna measurement chamber

Presents an integration of a shielded anechoic chamber environment for the spherical near-field antenna measurement purpose on developing the RFID static test system and provides critical characterization features for evaluating the RFID tag 3D operation performance requirements. The prototype system architecture for the static test system provides the methodology for measuring figures of merit of the tag readable range. This system is capable of performing realistic case measurements for detailed analysis requirements and to provide critical indicators based on the results for optimal RFID tag operation performance over full 3D circumference. The proposed 3D RFID static test system may be applied as an effective tool for optimal tag and reader operation performance developments.
