摘要

本文提出了一种基于频域无芯片传感技术的低轮廓湿度传感器。该无芯片微波传感器由微带谐振器与50Ω微带传输线间隙耦合组成，并加载了nationion 117敏感材料层。在固定温度(25°C)和相对湿度(RH)变化范围为0% - 90%时，传感器的响应进行了模拟和实验条件下的测试。初步结果是有希望的，并为未来深入表征传感器和分析现实条件下的性能铺平了道路。

A Preliminary Microwave Frequency Characterization of a Nafion-Based Chipless Sensor for Humidity Monitoring

A low-profile humidity sensor based on a frequency-domain chipless sensing technology is proposed in this study. The chipless microwave sensor is composed by a microstrip resonator gap-coupled with a 50Ω microstrip transmission line and loaded with a Nafion 117 sensitive material layer. The response of the sensor at fixed temperature (25°C) and for a relative humidity (RH) variation in the range 0% - 90% has been simulated and tested in experimental conditions. The preliminary results are promising and pave the way for a future in-depth characterization of the sensor and an analysis of the performance under real-world conditions.
