Compact Frequency Selective Surface Antenna for Grain Moisture Content Monitoring

In this paper, we propose a novel frequency selective surface (FSS) antenna for monitoring the moisture content (MC) in X-band (8–12 GHz). In the proposed sensor, the sample under test acts as the substrate of the antenna sandwiched between an array of square split ring resonators (SSRR) at the top plate and a ground plate at the bottom. The center frequency is chosen as 10 GHz. The width, length,...
