| Abstract: |
In this paper, a highly sensitive microwave patch sensor for detecting adulteration in olive oil is proposed. First, a broadband electromagnetic property of olive oil adulterated with corn oil is characterized by using a Cole-Cole function. Next, a microwave patch sensor is designed with a circular patch integrated with a meandered slot and a complementary split ring resonator (CSRR) in the ground plane. A prototype of the microwave patch sensor is fabricated to detect the adulterant in olive oil. The results indicate that the proposed microwave patch sensor can detect the adulteration ratio of corn oil in the parent olive oil ranging from 0 to 100%. The sensitivity, resonance frequency shift, and quality factors are 6.16%, 41 MHz, and 173, respectively. The proposed microwave patch sensor maintains a simple structure and an electrically small size (κα = 0.83), high sensitivity, low cost, and ability to fast detect adulterants for olive oil.
