1. A multi-layer antenna for an implantable medical device (“

  • IMD”

    ), comprising;

    a biocompatible antenna portion including;

    an antenna formed from a biocompatible conductive material, andat least one layer of biocompatible dielectric material; and

    a high dielectric portion including;

    a ground plane, andat least one high dielectric substrate having a high dielectric constant positioned between the antenna and the ground plane,wherein the at least one layer of biocompatible dielectric material in the biocompatable antenna portion includes a lower dielectric constant than the at least one high dielectric substrate in the high dielectric portion.
