Abstract

Microwave sensors are very attractive choices for many of electronic,biomedical and industrial applications.They offer many advantages including high sensitivity, robustness and low fabrication and measurement cost.High sensitivity and accurate identification of chemical and biological liquid samples using microwave dielectric and cylindrical resonators have been studied and demonstrated.In this paper,the main part of the device is a microstrip coupled complementary split-ring resonator (CSRR).The CSRR produced a strong electric field in a gap and the ring.The device is designed to operate at around 2 GHz.So it,satisfies the need for low-cost and compact high sensitivity devices in microwave microstrip sensor applications.The liquid sample drop at a ring modifies the resonance frequency and peak attenuation of the CSRR resonance.The microstrip sensor requires a very small amount of sample.The proposed microstrip sensing concept is compatible with lab-on-a-chip platforms owing to its compactness.
