Abstract
In one of several embodiments, an RFID system for a forklift incorporates a metal plate to which is attached an electronic circuit assembly. Also attached to the metal plate, is an antenna assembly housing an RFID interrogator antenna and/or a wireless local area network (WLAN) antenna. The metal plate operates as a ground plane to the antenna assembly and also serves as a mounting plate for mounting the RFID system on a sideshifter or a carriage of the forklift.
