Automated platform for characterization of RFID reader antennas

RFID systems have evolved from simple ones to complex equipment, but one of the most important components in their structure is the antenna. The overall system performance is highly depending on quality of the communication between antenna and transponders, so it is very important to characterize it with high accuracy. This paper presents an automated platform for antenna characterization based on automatic exploration of the usable area of antenna, using a transponder positioned on X and Y coordinates with two stepper motors and the associated mechanics.
