Abstract
An antenna for an implantable medical device (IMD) is provided including a monolithic structure derived from a plurality of discrete dielectric layers having an antenna embedded within the plurality of dielectric layers. The antenna includes antenna portions formed within different layers of the monolithic structure with at least one conductive via formed to extend through the dielectric layers in order to provide a conductive pathway between the portions of the antenna formed on different layers, such that an antenna is formed that extends between different vertical layers. The dielectric layers may comprise layers of ceramic material that can be co-fired together with the antenna to form a hermetically sealed monolithic antenna structure. The antenna embedded within the monolithic structure can be arranged to have a substantially spiral, helical, fractal, meandering or planer serpentine spiral shape.
