Tests Measurement of UHF RFID for Autonomous Vehicle Navigation

Abstract

This article provides a discussion of the testing and measurement of UHF RFID with distance and facing angle parameters on static and moving state conditions. This study is necessary for implementing RFID technology in the development of autonomous vehicle navigation systems. Navigation systems in autonomous vehicles generally never leave the global positioning system (GPS) as a navigation sensor. The use of GPS independently has weaknesses related to the accuracy, so a navigation system using GPS requires correction of the navigation route based on coordinates, this correction can be done by adding another sensor. The integration of GPS and RFID technology has several advantages besides being cost-effective. Studies that have been carried out enable an autonomous vehicle navigation system to be run by combining data between RFID Reader readings in retrieving location data points marked with RFID tags and coordinate vehicle position data on maps by the GPS which generates route and location information passed by vehicles using the GPS/RFID method localization. Tests and measurements are performed by reading on three types of RFID tags with varying distances and angles of view. The results showed that the best reading distance for RFID tags is at a distance of 4 meters with a reading angle of the RFID Reader at 90 degrees on the z-axis and y-axis. While the best RFID tag performance is the tag on the Passive UHF RFID metal, both for testing in static or moving state condition.
