915MHZ UHF RFID TAG FOR AUTOMOTIVE TIRE APPLICATION

Abstract

"Radio Frequency Identification (RFID) is widely used nowadays. It is really not a new technology at all. It has been implemented since 1970. It is evolved as a major technology enabler for identifying and tracking goods and assets around the world. RFID is being used in many industries such as transportation, manufacturing, security, finance.

RFID systems is adopted to track and control major assemblies within a production plant for more than 30 years in the automotive industry to control of flexible manufacturing processes by recognizing items being built on a production or labeling key components for later recycling. However, developing a RFID tag for automotive tire application is a key challenge for RFID developers to improve the efficiencies originating from inaccurate data about product or the inability to trace.

The main objective of this project is to design a miniaturized embedded UHF RFID Tag for Automotive Tire applications. The project focused on designing a Microstrip patch antenna with a high radiation efficiency because the current antenna design in the markets suffers low radiation efficiency, ranging from 50% - 60%. Three novel antenna designs are proposed and comparatively evaluated in terms of size, efficiency. The proposed 915MHz RFID tag employed far field coupling. The RFID tags will be embedded into tires, identifying information such as the manufacturer, time and date of manufacturing and specification of the tires. All of this information will be downloaded into the database once the tires are assembled into the car. The purpose of this RFID tag is to enable manufacturer to make targeted and quick recalls.

Agilent Advanced Design System (ADS) tool is used to perform a system simulation as well as to design and come up with particular antenna performance parameters such as directivity, radiation patterns, gain and efficiency. "
