Abstract
The invention relates to a RFID chip that is contained inside a rubber tire to provide wireless communication of information concerning the tire. For instance, it may be desirable to communicate pressure and temperature information concerning a tire during its manufacture and/or usage. The RFID chip is attached to the inside of the rubber tire and is capacitvely coupled to a conductive belt contained inside the tire to provide an antenna for radio-frequency communications and reception.
Claims32
A system for communicating information wirelessly with a tire, comprising:
- a tire that includes:
- an elongated planar surface having an inner side and an outer side forming a circular shape, wherein said elongated planar surface comprises a first outer edge and a second outer edge opposite of said first outer edge;
- a first planar side that connects to said first outer edge to form a first inner wall;
- and
- a second planar side that connects to said second outer edge to form a second inner wall;
- said elongated planar surface having embedded within at least one conductive belt to add structural integrity to said tire;
- and
- a RFID chip having at least one antenna pin, wherein said RFID chip is attached to said inner side of said tire and wherein said elongated planar surface forms a dielectric between said at least one conductive belt and said RFID chip;
- said at least one antenna pin capacitively coupled to said at least one conductive belt to form an antenna for radio-frequency signal communication to and from said RFID chip.
