ABSTRACT:
The present invention provides a tine-mounted antenna for reading RFID tags in a warehouse environment using RFID technology operating at ultra-high frequencies (UHF) or microwave frequencies and backscatter coupling techniques. At least one ruggedized antenna is mounted on the tine (or other base-level platform) of a lift truck (e.g., a forklift). The antenna can be configured to read RFID tags on pallets that are loaded on the lift truck and communicate the tag information to a warehouse management system.
