Abstract

An improved electronics device for a tire includes a radio device and an antenna intended to be attached to or embedded in a tire, the antenna being shaped to absorb tensile stress applied by the tire, and having a meandering shape. A preferred shape is a sinusoidal wave pattern. The antenna body may be a wire formed of spring steel, brass coated spring steel, or spring brass.

Claims

1. An improved electronics device for a tire of a vehicle, comprising:

a radio device for communicating information from said tire with a remote radio device; and

,

at least a first antenna wire connected to and extending from said electronics package, wherein, the at least first antenna wire is shaped to have at least one undulation for relieving tension applied in the direction of the at least first antenna wire.

2. The improved electronics device as claimed in claim 1, wherein said at least first antenna wire is shaped in a sinusoidal pattern.

3. The improved electronics component assembly as claimed in claim 1, wherein the at least first wire is shaped with a saw-tooth pattern.

4. The improved electronics device as claimed in claim 1, wherein the at least first wire is shaped in a square wave pattern.

5. The improved electronics device as claimed in claim 1, wherein the at least first wire is shaped in a single undulation.

6. The improved electronics device as claimed in claim 1, further comprising a second antenna wire connected to and extending from said electronics package and shaped to have at least one undulation for relieving tension in the at least second antenna wire.
