On the Influence of Impedance Matching for the Sensitivity of Reflection Phase Measurements with Resonant Sensors

Abstract

In this contribution, the influence of impedance matching for sensors that incorporate phase measurements in a one-port reflection setup is elaborated in detail. The developed theoretical basis is validated by three-dimensional electromagnetic simulations that are corroborated by reflection measurements of a metamaterial-based, resonant near-field sensor with varying impedance matching conditions.
