Abstract:
An antenna for an implantable medical device (IMD) is provided that is formed on the same substrate as the telemetry circuitry for the IMD. The telemetry circuitry is formed on a portion of the substrate within the interior of a housing for the IMD, while at least one antenna is formed on an exterior portion of the substrate on the exterior of the housing to allow for far field telemetry. At least one electrical interconnect is formed on the substrate for connecting the antenna to the telemetry circuitry, where the electrical interconnect may comprise a controlled impedance line to minimize loss. A conformally-shaped hermetic cover, such as a ceramic material, may be formed in a desired shape around the exterior portion of the substrate and antenna and cofired together to form a monolithic structure encasing the antenna and exterior portion of the substrate.
