Abstract: An implantable medical device may include each of a conductive canister, a printed circuit board assembly (PCBA), and a header. A feedthrough and ferrule couple the interior of the canister, where the PCBA is, to one or more elements contained in the header such as an antenna and/or a port for coupling to a lead. The ferrule may be directly attached to the conductive canister and the electronic circuit board. The electronic circuit board carries an RF transmitter for telemetry purposes, and has an RF ground plane layer therein. The ferrule is capacitively coupled to the RF ground plane the PCBA, and has a size and/or shape relative to the RF ground plane that provides sufficient capacitance to offer an improved RF ground plane path to the conductive canister at a desired telemetry frequency.

Abstract: A capacitively loaded loop antenna for an implantable medical device is disclosed comprising a feed extending from a conductive surface of an implantable housing, a radiating element having a cross section larger than the feed, and a return coupling the radiating element to a conductive surface of the implantable housing. The radiating element can have a height above the top surface of the implantable housing, creating a capacitance between the radiating element and the conductive surface of the implantable housing configured to counteract the inductance of the capacitively loaded loop antenna.
