摘要

介绍了两种用于无线RFID介质介电常数传感的平面传感器。第一个传感器由基板集成波导(SIW)谐振腔组成，第二个传感器由SIW Epsilon-Near-Zero (ENZ)隧道传感器组成。这两种结构都能产生4 GHz的陷波共振响应，用于使用腔微扰技术表征液体。所提出的传感器在使用少量样品体积的情况下具有良好的灵敏度。

Planar sensors for RFID wireless complex-dielectric-permittivity sensing of liquids

Two planar sensors for wireless RFID dielectric permittivity sensing of liquids are presented. The first sensor consists of a Substrate-Integrated-Waveguide (SIW) resonant cavity while the second one is composed by an SIW Epsilon-Near-Zero (ENZ) tunnel sensor. Both structures produce a notch resonance response at 4 GHz which is used for the characterization of the liquids using the Cavity-Perturbation-Technique. The proposed sensors present good sensitivity using a small amount of sample volume.
