Microwave sensors based on electrically small planar resonant elements are reviewed in
this paper. By virtue of the high sensitivity of such resonators to the properties of their …

The conventional resonant-type microwave microfluidic sensors made of planar resonators
suffer from limited sensitivities. This is due to the existence of several distributed capacitors …

A microwave microfluidic sensor for dielectric characterization of liquids in real time is
presented in this paper. The sensor is implemented in microstrip technology and consists of …

This paper presents a microwave sensor using a pair of split-ring resonators (SRRs). The
