AI Technical Summary

Benefits of technology

The solution effectively protects the antennas from vehicle traffic and environmental factors, ensuring reliable tire tracking by maintaining signal integrity and antenna functionality, even under repeated vehicle loads and harsh conditions.

Problems solved by technology

These trucks sometimes include eighteen or more tires, creating a large-scale tire tracking challenge.
This leads to a high possibility that the antennas may be run over by the truck tires several times a day.

Embodiment Construction

[0028] The following discussion of the embodiments of the invention directed to an antenna system including a support structure that encapsulates the antenna is merely exemplary in nature, and is in no way intended to limit the invention or its applications or uses.

[0029] Several embodiments of a vehicle tire interrogation system including DBUs positioned on or in the ground are discussed below, where the DBU includes an antenna that interrogates a radio frequency identification (RFID) sensor and / or temperature and pressure sensors embedded in a vehicle tire. The antenna transmits and receives RF signals to and from the RFID sensor and the temperature and pressure sensors. For one particular vehicle tire interrogation system, the antenna is dual band, operating in the 433.05-434.79 MHz frequency band and the 902-928 MHz frequency band. The antenna also has an input impedance of 50 ohms at both frequency ranges, is horizontally polarized, and has a gain of a minimum of 2 dBi at 434 ...

Abstract

An antenna system that is positioned within a support structure. The antenna system includes at least one antenna that may have one or more antenna elements formed on a substrate. The support structure encloses the antenna and includes an outer support portion defining a cavity and an inner support portion positioned within the cavity. The antenna is positioned within the cavity between the outer support portion and the inner support portion so that the antenna is substantially surrounded by air.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a Continuation application of U.S. Utility patent application Ser. No. 10 / 954,555, titled Antenna System Embedded In A Support Structure For Interrogating A Tire Sensor Transponder, filed Sept. 30, 2004 which claims priority to U.S. Provisional Patent Application No. 60 / 508,251, titled Antenna System Embedded in a Support Structure for Interrogating a Tire Sensor Transponder, filed Oct. 2, 2003.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates generally to an antenna system and, more particularly, to an antenna system positioned within a support structure and substantially surrounded by air. [0004] 2. Discussion of the Related Art [0005] Heavy trucks and other vehicles are extensively used to transport passengers and goods. These trucks sometimes include eighteen or more tires, creating a large-scale tire tracking challenge. An efficient tire tracking system would speed up inv...
