SYSTEMS AND METHODS FOR A RFID ENABLED METAL LICENSE PLATE

摘要

In the embodiments described herein, a RFID enabled license plate is constructed by using the license plate, or a retro-reflective layer formed thereon as part of the resonator configured to transmit signals generated by and RFID chip integrated with the license plate. Such an RFID enabled license plate can include a metal license plate with a slot formed in the metal license plate, and a RFID tag module positioned in the slot. The RFID tag module can include a chip and a loop, and the loop can be coupled with the metal license plate, e.g., via inductive or conductive coupling. In this manner, the metal license plate can be configured to act as a resonator providing increased performance.

主权项

1. A radio frequency identification (RFID) enabled license plate, comprising:
a metal license plate having formed thereon a first slot that is perpendicular to a second slot; and an RFID strap comprising an RFID chip, wherein the first slot and the second slot are configured such that a slot antenna formed from the metal license plate resonates at a first frequency and a second frequency, wherein the second slot extends linearly from between both edges of the first slot, and wherein the RFID strap is disposed over the second slot in a same plane as and parallel to the first slot.
