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.
