Microstrip ring resonator based sensing technique for meat quality

Dielectric properties of material are being used in various industrial applications. In food industry, its usage is increasing day-by-day especially for meat products. In this paper for quality evaluation of meat, microstrip ring-resonator is presented as a sensing technique; which is simple, cost-effective and faster than other techniques. The multilayer structure of 1 GHz microstrip ring-resonator is designed and then simulated with an overlay meat sample, using high frequency structure simulation (HFSS) software. From simulation results, it is observed there is a noticeable shift in the resonant frequency (~40 %); i.e. changing its effective permittivity. Simulation results are then validated with numerical results, where the minimum difference observed is 1.04 %.
