ABSTRACT:
A card assembly (10) comprises a polymeric layer (16) having a generally planar surface (24), an integrated circuit component (38) adjacent to the polymeric layer (16), and a loop antenna (24) formed of a bare conductor (32) having ends. The loop antenna (24) comprises a first section (26) embedded into the polymeric layer (16), a second section (28) embedded into the polymeric layer (16), and a transverse section (30) spaced apart from the first section (26) by a dielectric region. The transverse section (30) crosses the first section (26). The ends (34) are electrically coupled to the integrated circuit component (38). The dielectric region preferably comprises a reflowed flash region of the polymeric layer (16) such that the transverse section (30) is encapsulated within the polymeric layer (16). Alternately, the dielectric region comprises a dielectric insert separating the transverse section from the first section.
