An antenna apparatus for an implantable medical device is adapted and disposed to have an increased telemetry range by providing a plurality of antennas connected in parallel with each other, and physically separated from each other. The antennas may be mounted within the IMD can or they may be located externally, outside the IMD can, but associated and mounted to the IMD can package. The antennas may have coils wound around an air-core or a non-air core such as ferrite. There can be any number of them but it is preferrably a number between 1 and 10.
