Abstract
This paper presents a review on characterization of agricultural product using various type of microwave sensor. Interaction between EM waves with materials are described. Interaction between microwave and agricultural product are considering a wide range of frequencies and applications such as detection of dielectric properties, moisture content, heating mechanisms, and product control. Each of the Agricultural product has their unique dielectric properties, it can be characterized by frequency dependent parameters such as dielectric properties and moisture content. By analyzing the unique dielectric properties of the agricultural products, the moisture content and the heating mechanisms can be distinguished by measuring the changes in dielectric properties and concentration of agricultural products. Additionally, this paper also emphasis on a clear demarcation of open-ended coaxial probe, planar antenna, rectangular waveguide, and horn antennas as microwave sensor and their applications.
