All-Ceramic mm-Wave Chipless Sensors for Wireless Temperature Sensing over 1000 °C in Cluttered and Obstructed Environments

Popis výsledku v původním jazyce

Millimeter-wave (mm-Wave) chipless and wireless sensors capable of continuous operation under extreme environmental conditions remain largely unavailable, particularly for dynamic scenarios involving high temperatures and strong electromagnetic clutter. We have recently presented a fully dielectric, wireless temperature sensor specifically designed for operation beyond 1000 °C. The sensor is based on high-Q resonant cavities embedded within a three-dimensional photonic crystal structure, exhibiting two resonance peaks at 83.5 GHz and 85.5 GHz. To enhance the Radar Cross Section (RCS) and interrogation range, a flattened Luneburg lens is integrated in the sensor. The device is fabricated using Lithography-based Ceramic Manufacturing (LCM) with Alumina (Al₂O₃). Measurements demonstrate that the frequency-coded backscattered signal remains detectable at distances up to 50 cm and temperatures up to 1200 °C. The resonance frequencies exhibit a temperaturedependent shift, which is in good agreement with Al₂O₃ values reported in the literature. A similar sensor has been demonstrated with a one-dimensional photonic crystal, demonstrating the suitability of these chipless RFID sensors in harsh environments.
