Sensitivity investigation of coupled-line microwave sensor on dielectric material-under-test

摘要

In this paper, sensitivity analysis of the recently developed coupled-line sensor has been presented. The proposed sensor allows for detection of dielectric materials permittivity change in a wide frequency range, which is an essential property for e.g. environmental monitoring. The previously conducted theoretical investigation of the sensitivity has been now confirmed by experimental results, proving correctness and usefulness of the presented approach.
