Abstract

A UHF antenna for an implantable medical device comprises a conductor which may be adjusted to resonate at the frequency allocated to implantable medical devices, and the metal case of the device as a counterpoise. A connected end of the conductor is electrically connected to the case and the conductor circles partially around the case from the connected end to an open end. The open end may be adjusted to tune the center frequency of the antenna. A radial feed-point between the connected end and the open end may also be adjusted to tune the center frequency of the antenna. The conductor may have a round or flat cross-section. An insulating material separates the conductor from the case and holds the conductor in place.
