| Summary: | In this paper, a new type of microwave sensor for determining and detecting the dielectric properties in common solid such as meat is proposed. Various resonators such as coaxial cavity, dielectric, and waveguide resonators have been used for material characterization. However, these resonators are often large in size, expensive, and they have low sensitivity with poor Q-factor. Thus, a new planar resonator technique is presented in order to have higher Q-factor. This type of sensor is based on perturbation theory, in which the dielectric properties of the resonator effect the quality factor and resonance frequency of the microwave resonator. A microstrip of symmetrical split ring resonator (SSRR), which has two gaps, is adopted for the design of the sensor. This resonator is suitable for various industry applications such as food industry, quality control, bio –sensing medicine and pharmacy. A very good agreement is illustrated between the calculated and simulated results at operating frequency of 2.2 GHz. In addition, a high sensitivity is achieved in the same operating resonance frequency by using High Frequency Structure Simulator (HFSS) |
