Sticker transponder for use on glass surface |
摘要 |
A sticker transponder adapted to be affixed to a glass surface, such as a vehicle windshield, includes a RFID transponder enabling the storage and retrieval of vehicle related data. The sticker transponder comprises a flexible circuit substrate having an antenna formed thereon and a transponder circuit disposed on the substrate and coupled to the antenna. An adhesive layer is coupled to a first surface of the flexible circuit substrate. An indicia layer is coupled to a second surface of the flexible circuit opposite from the first surface. The indicia layer comprises a space permitting indicia to be printed thereon. The antenna has a characteristic impedance defined in part by a dielectric constant of the flexible circuit substrate in combination with a dielectric constant of the glass surface. As a result, a proper impedance match between the antenna and the transponder circuit is achieved only when the sticker is affixed to the glass surface. The sticker transponder further comprises a release liner affixed to the adhesive layer, the release liner being selectively removable to permit the sticker transponder to be affixed to the glass surface. The transponder circuit further includes a memory having a read-only portion and a re-writable portion.
