Abstract: An implantable medical device (IMD) configured for implant in a body includes an enclosure that houses communication circuitry, an antenna, a dielectric layer, and a transmission line. The enclosure includes an outer surface configured to be oriented in a direction facing the exterior of the body and to be placed adjacent tissue. The antenna includes a ground plane corresponding to the enclosure, a dielectric spacer that conforms to the outer surface of the enclosure, and a radiating element that conforms to the dielectric spacer. The dielectric layer overlays the radiating element and the dielectric spacer. The transmission line is electrically connected between the radiating element and the communication circuitry.
