This work aims to present an improved version of the liquid mixture identification sensor, the proposed sensor is tested experimentally on mixture of water ethanol, the identification of liquid is based on the measurement of frequency displacement, and comparison with reference values of water ethanol. This device is based on metamaterial structure which is a composite right left hand (CRLH) resonator with zero-order resonator (ZOR). The CRLH in addition to its property of miniaturization effect, when combined with ZOR, the resonant frequency of various volume fraction are extended, which make the sensitivity higher. The high sensitivity of the sensor is obtained by an optimum choice of the CRLH components. The geometrical size of the sensor is 20 mm by 11 mm. It was printed on a RT/Duroid 5880 substrate with a very short testing surface area of 4 mm by 8 mm, the liquid is placed on the top side of the sensor, exactly on the CRLH structure. Three prototypes of sensors operating from 1 to 3 GHz are proposed, designed and simulated using the commercial software high-frequency structural simulator (HFSS). The main advantages of this work is first miaturization effect, second high sensitivity and finally a wide range of liquid can be tested with this sensor. To prove the working principle, ethanol with different volume fractions was adopted as a liquid under test, the obtained results present very good agreement with the literature and suggested that it is a miniaturized and high sensitive candidate (better than 1.38%) for liquid mixture identification.

“…The substrateintegrated waveguide (SIW) is a type of antenna where a waveguide is built on the top of the substrate, and the main advantages of these antenna are lower losses and better power handling [4,5]. The metamaterial antennas (MTMs) are based on artificial materials that have uncommon physical properties, such as negative permittivity or negative permeability; these types of antennas have many advantages, such as higher gain, wideband of frequency, and miniaturization effect [6].…”

The chapter presents different types of metamaterials, their historical evolution, physical properties, and applications in antennas design. Metamaterials are artificial structures that offer electric and magnetic properties that are not found in nature, such are negative permittivity and negative permeability. These properties are used in antennas design in order to obtain ultrawide bandwidth, high gain, and electrically small structures. Modern wireless mobile communication uses 5G technology and multi-input multi-output (MIMO) antennas, which are based on high-frequency transmission and ultrawide band. Metamaterials are very good candidate for this technology, where miniaturized antennas loaded with metamaterials structures are used. Recently, electromagnetic sensors were used for liquid identification in biological and medical substances based on metamaterials for the sake of high sensitivity and better classification. Different metamaterial types are used in these sensors, depending on the nature of liquid and the associated application.

“…Metamaterials based structures are very important microwave components that are used in sensor designs. They are also used in a very wide frequency range, including microwaves [3][4][5], terra-hertz [6] and optics [7]. The type of substances that are tested on these sensors can be liquid solid dielectrics [7], and bimolecular [8].…”

In this work, we propose a metamaterial-based microwave sensor. The main body of the proposed sensor is a microstrip coupled complementary spiral rectangular resonator (CSRR). At resonance, a strong electric field is established along the sides of the CSRR creating a very sensitive area to change in the nearby of the dielectric environment. The enhanced proposed contactless sensor uses liquid samples placed normal to the sensor surface retained within capillary glass tubes. Quick analysis of the liquid dielectric properties is carried out by simply replacing the capillary tube with a new sample.The introduced liquid sample shifts the resonance frequency and alters the peak attenuation of the CSRR resonance. The liquid sample dielectric properties may be estimated by establishing an empirical relationship between the resonance characteristics and the liquid complex relative permittivity. In this work, we could improve our device by simple changing of the CSRR shape of a recently published work, this makes improvement on the characteristics of the sensor and lower its working frequency to 1.8GHz.
