An implantable medical device has a conductive housing containing circuitry for operation of the device and radio frequency circuitry for transmitting and/or receiving radio frequency signals. An insulating header is arranged adjacent to the conductive housing. A conductive structure is provided on a surface of, and/or within, the insulating header. An antenna feed is operatively interconnected between the radio frequency circuitry and the conductive structure. The conductive structure is galvanically connected to the conductive housing, and the conductive structure and the conductive housing, in combination, operate as a transmitting and/or receiving antenna for the radio frequency signals. |
