Implantable medical devices having cofire ceramic modules and methods of fabricating the same
First Claim
1. An implantable medical device (IMD), comprising:
- a housing configured for one of human implant or being worn on a body; and
a cofire ceramic module coupled to the housing, wherein the cofire ceramic module includes an antenna cofire-integrated in the cofire ceramic module, the antenna comprising;
a plate composed of conductive material;
a plurality of layers of conductive antenna elements, the plurality of layers of conductive antenna elements being annular substrates having perimeters substantially coextensive with a perimeter of the plate;
a plurality of interconnections, wherein the plurality of interconnections comprise;
a first set of interconnections coupled between the plate and the conductive antenna element of one of the plurality of layers of conductive antenna elements; and
a second set of interconnections coupled between the conductive antenna elements of the remainder of the plurality of layers of conductive antenna elements; and
a feed line conductively coupled to the plate.

Abstract
An implantable medical device (IMD) and methods of fabricating the same are provided. An IMD can include a housing and a cofire ceramic module (CCM) coupled to the housing. The CCM can include an antenna cofire-integrated in the CCM. The antenna can include a plate composed of conductive material, and conductive antenna elements that are annular substrates having perimeters substantially coextensive with the perimeter of the plate. The antenna can also include interconnections. A first set of interconnections can be coupled between the plate and one of the conductive antenna elements, and a second set of interconnections can be coupled between the conductive antenna elements. The antenna can also include a feed line conductively coupled to the plate. In some embodiments, the feed line can be substantially serpentine-shaped to adjust impedance in the CCM.
