This paper presents a highly sensitive phase-variation sensor for dielectric constant measurements based on a capacitively-loaded periodic slow-wave transmission line. Such line is implemented in microstrip technology, and the loading capacitors are formed by closely spaced rectangular patches.

IEEE Transactions on Microwave Theory and Techniques
This article presents a strategy for implementing highly sensitive planar microwave permittivity sensors operating in transmission and based on the measurement of the phase of the transmission coefficient at a single frequency. The idea is to shunt-connect a sensitive element to the host line exhibiting a zero (resonance) and a pole (antiresonance ...

IEEE Sensors Journal
This article presents a sensor able to detect small changes in the dielectric constant of its surrounding with regard to a reference (REF) value. The sensor operates in transmission, is fed by a single-frequency (harmonic) signal, and uses the phase of the transmission coefficient at that frequency as the output variable.

A Method to Retrieve the Output Variables in Reflective-Mode Phase-Variation Sensors
2022 52nd European Microwave Conference (EuMC), 2022In this paper, a method to retrieve the relevant information, i.e., the phase and magnitude of the reflection coefficient, in reflective-mode phase-variation sensors is reported. By using a pair of rat-race hybrid couplers conveniently connected, and with the ports appropriately loaded, including the one-port sensing load, the reflection coefficient of
