In this work, we investigated the feasibility of using a microstrip sensor to monitor milk quality. The proposed microstrip sensor is composed of two symmetrical and independent rectangular microstrip patches. This method is based on a shift in the resonance frequency of the microstrip resonator caused by a change in the dielectric constant of the analysed milk. Simulations and measurements were performed in the study. The results indicate the effectiveness of the proposed microstrip patch in product quality assessment.

微带传感器，用于产品质量监控

在这项工作中，我们调查了使用微带传感器监测牛奶质量的可行性。提出的微带传感器由两个对称且独立的矩形微带贴片组成。该方法基于微带谐振器的谐振频率的偏移，该偏移是由分析牛奶的介电常数的变化引起的。在研究中进行了模拟和测量。结果表明所提出的微带贴片在产品质量评估中的有效性。
