Nowadays, chemical sensors have widespread applications in various fields such as biomedical, pharmacy, food industries and petrochemical industries. These sensors, based on their performance and components, are categorized into different types and microwave passive sensors are considered as one of them. Microwave sensors usually do the evaluation process by using changes created in frequency response due to presence of different samples. One of the important parameters, which is used for assessment of sensors performance, is their sensitivity to characteristics changes of sample. In this thesis, as a novel application of SSPP-based structures in microwave frequency band, a chemical sensor has been designed which benefits from high sensitivity rely on near-field nature of SSPPs. Also, for liquids placement on sensor surface, a microfluidic structure has been used and embedded on sensor. Eventually, in order to evaluate sensor performance and its sensitivity, it has been fabricated and five samples of non-polar liquids including petrol, paraffin oil, frying oil, sesame oil and olive oil has been tested using the embedded microfluidic channel.
