Low-Cost and High Performance Antenna Setup for Updating ePaper Displays on Curved RFID SmartTags Used in Pharmaceutical Studies

This work presents a scalable RFID antenna setup used to update passive SmartTags mounted on round containers. Examples where this technology can be highly beneficial are pharmaceutical studies. The reader antennas are placed under the containers and are designed to ensure RFID communication and power transfer independent of container rotation with multiple containers in close proximity. The effects of the proposed antenna setup on the system are analyzed both theoretically and in simulations. Measurements are performed to verify the results and to demonstrate the system.
