摘要：
Subject matter such as a method or apparatus can include an implantable medical device comprising a housing, an implantable telemetry circuit carried within the housing, and a dielectric compartment, mechanically coupled to the housing an implantable telemetry antenna, such as located at least partially within the dielectric compartment. The implantable telemetry circuit can be electrically coupled to the implantable telemetry antenna and configured to wirelessly transfer information electromagnetically using the implantable telemetry antenna. The implantable telemetry antenna can include a spiral conductor portion extending along a face portion of the dielectric compartment, and a loading portion configured to adjust an input impedance of the implantable telemetry antenna, to provide a specified input impedance range within a specified range of operating frequencies to be used for wireless information transfer.
