Microwave Sensor for Liquid Concentration Measurement
Problem and implemented solution
Metamaterial-based sensors have been received great attention due to their high sensitivity and miniaturized size for determining the permittivity. This project presents the design and simulation of a metamaterial microwave sensor operating as a dual band sensor at 2.2GHz and 3.3GHz to determine the liquid ratio in water. The sensor was designed with split ring resonators(SRRs) and an electronic inductance circuit(ELC) resonator in the defected ground structure(DGS). The slot in the transmission line coupled with two half-ring are used for generating the resonances and the photonic band gap(PBG) structures to enhance the quality factor and improve sensitivity. The gaps in the ELC section are considered to have dual band characteristic.
