Description

Development of fast, accurate, mobile and low-cost tools for food analysis is an important topic to mitigate food-borne diseases. In this paper, a portable sensors based on S11 and S21 of compact circularly polarized antennas is proposed. A low-cost and portable VNA analyser is used to perform measurement and analysis. Fruits are used to assess the test-bed capability to classified different species. A raw of measurement using Orange, Tomato and Mango demonstrates that a signature for each species can be extracted. First results show the reflection coefficient isless sensitive than transmission coefficient to fruit position.
