Abstract
An implantable medical device and method are provided for implant within a patient. The device comprises a case. Radio frequency (RF) communication components are housed within the case. A header is mounted to an exterior surface of the case along an edge of the case. An antenna is coupled to the RF communication components. The antenna has an inverted E shape. The inverted E shaped antenna is within the header. The inverted E shaped antenna includes a conducting arm joined to first, second and third branches that are oriented within the header to extend toward the edge of the case underneath the header. The first branch of the antenna is conductively open and, no more than weakly coupled, with respect to the case. The second branch is located between the first and third branches. The second branch is configured to convey an RF signal feed. The third branch has a shunt to ground connection to the case. The case forms a ground plane for the antenna.
