A radio frequency identification (RFID) device includes a conductive
pattern, such as an antenna, on one side of a substrate, and a chip, such
as part of a strap, electrically coupled to the conductive pattern, and
either on an opposite side of the substrate or on the same side of the
substrate as the antenna. A method of fabricating the RFID device may
include crimping the strap onto the substrate, in contact with a seed
layer, which is subsequently used in forming the antenna or other
conductive pattern by plating. The seed layer may be a patterned
conductive ink layer. Alternatively, the seed layer may be a layer of
conductive material deposited on the substrate, such as by vacuum
deposition. Parts of the deposited layer may be covered with a patterned
mask in order to form the desired configuration of the conductive
pattern.
