摘要

本文介绍了一种基于谐波射频识别(RFID)标签的新型无源温度测量传感器，该标签使用肖特基二极管的温度灵敏度作为产生谐波的主要组件。谐波传感器的设计是基于这样一个事实，即二极管是一个非线性器件，当在一个基频上激发时，会产生该信号的谐波。在这种情况下，由于二极管热电压随温度变化，产生机制对温度敏感。测量结果证明了传感器的性能。

Harmonic RFID Temperature Sensor Design for Harsh Environments

This letter presents a new passive sensor for temperature measurements based on a harmonic radio-frequency identification (RFID) tag that uses the temperature sensitivity of Schottky diodes as the main component for the generation of harmonics. The design of the harmonic sensor is based on the fact that the diode is a nonlinear device that when excited at one fundamental frequency generates harmonics of that signal. In this case, the generation mechanism is sensitive to temperature due to the diode thermal voltage variation with temperature. Measurements prove the performance of the sensor.

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
