Electronics device for a tire having an extensible antenna and a tire having such a device
First Claim
1. An improved electronic communication device for a tire of a vehicle, comprising a radio device for communicating information from the tire to a remote radio receiver, and at least a first antenna wire connected to and extending from said radio device, the at least first antenna wire is formed with a plurality of helical turns, characterised in that the at least first antenna wire is coated with an electrically insulating material to isolate it from the tire rubber.

Abstract
An electronic communication device for a tire includes a radio device and an antenna intended to be attached to or embedded in a tire, the antenna being spirally or helically shaped to absorb tensile and bending stress applied by the tire. The antenna body may be a wire formed of spring steel, brass or zinc coated spring steel, or spring brass. A coating of insulating material coats the radio device and antenna for mounting on or in, and operation in, a tire structure.
