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.
Claims20
An annular apparatus comprising:
- a transponder;
- an annular antenna coupled to the transponder;
- a carrier strip formed of non-conductive material at least partially encapsulating the antenna and the transponder to maintain the antenna in a prescribed orientation relative to the transponder.
An annular apparatus comprising:
- a transponder for monitoring at least one parameter in a tire;
- an annular antenna coupled to the transponder;
- a carrier strip formed of non-conductive material at least partially encapsulating the antenna and the transponder to maintain the antenna in coupled relationship with the transponder.
A method for mounting an annular antenna and transponder to a tire, comprising the steps:
- providing an annular antenna;
- coupling a transponder to the annular antenna;
- encapsulating at least part of the antenna and transponder within a carrier strip of non-conductive material to create a ring assembly;
- and
- attaching the ring assembly to a sidewall region of the tire.
