Reflective-Mode Phase-Variation Sensors Based on a Movable Step Impedance Resonator (SIR) and Application to Micrometer-Scale Motion Sensing

IEEE Transactions on Microwave Theory and Techniques
This article proposes a novel reflective-mode phase-variation sensor based on a movable step impedance resonator (SIR) implemented in coplanar waveguide (CPW) technology. The sensing principle is the variation of the phase of the reflection coefficient at a specific (operating) frequency generated by SIR motion.

Highly Sensitive Coplanar Waveguide (CPW) Reflective-Mode Phase-Variation Permittivity Sensors Based on Weakly Coupled Step-Impedance Resonators (SIRs)

IEEE Transactions on Microwave Theory and Techniques
This article presents a small-sized and highly sensitive planar microwave permittivity sensor based on a pair of weakly coupled step-impedance resonators (SIRs), the sensing elements. The sensor, a one-port structure, is implemented in coplanar waveguide (CPW) technology, and it operates in the reflection mode. The sensing principle is the variation in
