Abstract

This paper presents a novel antenna combination for wireless physical measurements by using Surface Acoustic Wave (SAW) resonators on rotating machinery. The interrogation system is composed of a transceiver based on the RADAR strategy, connected to a magnetic loop antenna. A temperature SAW sensor working in the Industrial, Scientific and Medical (ISM) band [433.05 MHz - 434.79 MHz] is embedded on a three centimeters diameter steel axis and connected to a ceramic chip antenna allowing the wireless interrogation in this particular environment. Simulation, transmission and dynamic temperature measurement results are presented.
