Abstract
An annular antenna loop is electrically coupled to a transponder. The antenna and the transponder are at least partially embedded into a non-conductive carrier strip to form a ring assembly to render the antenna and transponder package unitarily transportable. The annular assembly affixes to a tire in a post-manufacture attachment procedure and at a location that minimizes exposure of the annular apparatus to strain and to electromagnetic interference from the metallic wheel rim.
