An implantable medical device for delivering a medical therapy or for monitoring physiologic parameters. The device is provided with a hermetic housing containing a transceiver coupled to an antenna located outside the housing by means of a feedthrough, mounted to the housing and coupled to the transceiver. The antenna takes the form of a length of conductor, coupled to the feedthrough. In some embodiments the antenna is an insulated stranded conductor coupled to the feedthrough by means of a metallic loading tab. In other embodiments the antenna includes a length of conductor encased in a dielectric, extending from the feedthrough, and a coaxial shield coupled to the housing and extending along only a portion of the length of conductor.
