Summary: | This paper presents a microwave sensor design for moisture detection contents in petroleum productions based on metamaterials. The proposed sensor occupies a compacted size of 40×40×1.6 mm3 by using low-cost FR4 substrate. The proposed sensor consists of a transmission line and two split-ring resonators (SRRs) mounted on two sides. The transmission line is coupled to the outer ring of the SRRs to provide two resonant frequencies at 1.03 GHz and 3.04 GHz. It is observed that most of the electric fields fringing is come out of the air gap on the SRRs. Two pans are mounted on the sensor to contain the sample under test (SUT). The simulation studies are carried out by using the Computer Simulation Technology (CST) Microwave studio. After introducing the pans, frequency shifts, △f1=150 MHz and △f2=424 MHz, are detected in the resonant frequency which is associated with the perturbation phenomenon when the water concentration is varied from 0% to 100%. The proposed sensor exhibits a reliable detection percentage of various different amounts of the moisture content in crude oil introductions. Generally, a good detection methodology is discovered by applying the proposed sensor for detecting the crude oil quality productions. |
