This article proposes a highly sensitive two-port single-frequency permittivity sensor operating in transmission. The device consists of a shunt-connected short-circuited quarter-wavelength resonator (the sensing element) sandwiched between a symmetric configuration of cascaded impedance inverters with alternating high and low impedance.

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.

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
