Abstract
A termination contact for an antenna that has a Ni--Ti radiating element is formed by a layer of electrically conductive carbon filler disposed on the Ni--Ti radiating element. A conductive element is positioned on the layer of conductive carbon filler to provide electrical interface between the Ni--Ti radiating element and external RF circuitry. In to prevent contamination, a protective layer of silicon elastomer covers the conductive layer and the Ni--Ti radiating element such that a portion of the conductive element is exposed to provide a RF feed point.
