This letter presents a differential microwave permittivity sensor based on the reflection coefficient of microstrip lines terminated with series <inline-formula> <tex-math notation="LaTeX">$LC$ </tex-math></inline-formula> resonators. A <inline-formula> <tex-math notation="LaTeX">$50~\Omega $ </tex-math></inline-formula> resistor is considered in series with the resonator. At resonance, the transmission line experiences a matched load causing a reflection zero. Two identical sensing elements are used for differential sensing, providing the possibility of simultaneous two samples detection. A prototype of the sensor is fabricated and measured around 2 GHz for validation of the differential sensing principle.
