| Summary: | This letter presents a high efficiency and accurate measurement of microwave resonator sensor using microstrip planar structural technology. The structure is designed based on the bridge split ring topology. The sensor has the ability to characterize liquid solvents using the extraction of polynomial fitting technique. The bridge equivalent circuit configuration allows the electromagnetic wave to focus on the sensing medium in order to gain high electric flux density, thus react as pushing effect for high Q factor. The bridge structure amplifies the electric field distribution. As demonstrated by the results, the unloaded Qu -factor improves more than 400 over the narrow bandwidth at operating frequency of 2.3 GHz, and provides less than 10-dB insertion loss. By comparison, this design has an identical performance goal and provides excellent sensing capability which can be implemented in pharmaceutical, biomedical, and beverage industries application. |
