| titleOfInvention | Contactless smartcards with coupling frames |
| abstract | A smartcard (SC) having at least a contactless interface, such as having a dual interface transponder chip module (TCM) with a chip (IC), a module antenna (MA) for the contactless interface, and contact pads (CP) for a contact interface. Metal layers (ML) may have openings (MO) for receiving the module, and slits (S) or nonconductive stripes (NCS) extending to the openings, thereby forming coupling frames (CF). A card body (CB) for the smartcard may comprise two such metal layers (front and rear coupling frames) separated by a layer of non-conductive (dielectric) material. A front face card layer and a rear face card layer may complete a multiple coupling frame stack-up for a smartcard. Various slit designs (configurations, geometries) are described and illustrated. The slit may be filled. The slit may be reinforced. |
