1. A contactless transponder, comprising:
- a substrate having a planar surface;
an antenna made from a conductive material disposed on said substrate, said antenna having a surface remote from said substrate that defines a plane parallel to said planar surface of said substrate; and
a chip structure comprising an integrated circuit chip and electrical contacts, said chip structure being mounted on said surface of said antenna such that a portion of said chip structure is embedded in the material of said antenna, and at least a portion of said integrated circuit chip protrudes above said surface of said antenna.
