AB - In this paper, the introduction of a novel microwave-aided sensor for the dielectric parameter characterisation of various amounts of adulterated mustard oil is presented. The suggested sensor is made of a FR4 substrate and has two square-shaped resonators with a cavity area inside of it. The manufactured sensor is 60 mm × 60 mm and operates between 1 and 5 GHz. A satisfactory correlation is found between numerical evaluation and experimental verification of the quantitative sensing performance. The central portion of the main sensing device of the suggested microwave sensor is empty to accommodate a disposable 3D printed cap, which is one design innovation. Due to this small cavity, it is possible to drop small quantities of liquid samples (~ 1 ml) without having to replace the entire microwave sensor circuit for each sample under test (SuT). The primary characteristic to be associated with the dielectric properties of the liquid samples is the stop band frequency, which is altered when SuT drop into the centre section of the microwave sensor. The suggested device’s measured sensitivity for detecting oil adulteration is 0.1. Also, it offers the technical potential to be used as high-quality benchmarking equipment for checking adulteration of mustard oil.
