A Single-Antenna Wireless Passive Temperature Sensing Mechanism Using A Dielectrically-Loaded Resonator

Keywords

Abstract

A novel wireless temperature sensing mechanism is proposed using a cylindrical cavity resonator loaded with temperature dependent dielectric material. The dielectric constant of the high temperature ceramics increases monotonically with temperature. Therefore, the temperature can be extracted by measuring the change in resonant frequency of the resonator. In order to receive and send signals wirelessly, a patch antenna is connected to the cavity resonator. The resonant frequency of the sensor changes from 11.35 to 11.02 GHz as the dielectric constant of the ceramic material is increased from 4.8 to 5.1. This design benefits from its compact size and has wide advantages in turbine applications. © 2012 IEEE.
