Abstract
An RFID transponder is embedded in a glass surface, such as a vehicle windshield, to provide for the storage and retrieval of vehicle related data. In an embodiment of the invention, the RFID device comprises a flexible circuit substrate with an antenna formed thereon and a transponder circuit disposed on the substrate and coupled to the antenna. In a multi-layer glass panel, the RFID device is disposed between adjacent ones of the glass layers and becomes embedded therein upon lamination of the glass layers together. Alternatively, the RFID device may be formed using one of the glass layers as a substrate, thereby avoiding the need for a distinct substrate layer. Where a glass panel has a transparent conductive layer for thermal insulation, the transparent conductive layer may be used to form a conductive portion of the RFID device. In a single layer glass panel, the RFID device is embedded into the glass while the glass is in a molten or plastic state.
