Abstract

An aircraft tire has a pair of bead sections, sidewall sections extending from the bead sections, and a tread section extending between the sidewall sections; the aircraft tire includes an RFID tag having a tag main body (IC chip) configured to store information about the aircraft tire, and an antenna extended from the tag main body, wherein, in a tread surface view, the antenna is disposed such that an extending direction of the antenna is parallel to a tire width direction or intersects the tire width direction within a predetermined angle range, and the aircraft tire satisfies a configuration 0.1<L/W<0.2, where a width of the aircraft tire is denoted as “W” and a total length of the antenna in the extending direction of the antenna is denoted as “L”, and when a diameter of the aircraft tire is 21 inches or more.

First claim

The invention claimed is:

1. An aircraft tire having a pair of bead sections, sidewall sections extending from outer side in a radial direction of the bead sections, and a tread section extending between the sidewall sections, the aircraft tire comprising:
an RFID tag comprising: a tag main body configured to store information about the aircraft tire, and an antenna extended from the tag main body, wherein
a diameter of the aircraft tire is 21 inches or more,
the tag main body and the antenna of the RFID tag is sealed within a rubber patch and the rubber patch is attached to the tire inner surface of the tread section by an adhesive,
the antenna is a monopole antenna or a dipole antenna,
the antenna is disposed such that an extending direction of the antenna is parallel to a tire width direction or intersects the tire width direction within 5 degrees in a tread view, and
the aircraft tire satisfies a configuration 0.1<L/W<0.2, where a width of the aircraft tire is denoted as “W” and a total length of the antenna in the extending direction of the antenna is denoted as “L”, and when a diameter of the aircraft tire is 21 inches or more.

2. The aircraft tire according to claim 1 , wherein the monopole antenna or the dipole antenna has a linear shape or wavy line shape.

3. The aircraft tire according to claim 1 , wherein the RFID tag is disposed circumferentially apart form a balance patch provided on the tire inner surface.

4. The aircraft tire according to claim 1 , wherein a belt part disposed in the tread section is made of a non-metal material.
