Design and Analysis of Microstrip Patch Antenna with DGS for Determination the Moisture Content in Grains

The proposed design is analysis for determination of moisture content at operated microwave frequency 1.7GHz with the good return loss -15dB. The proposed design will be fabricated on FR-4 substrate which is low cost as well as substrate with 4.3 permittivity and 1.676mm thickness. The width and length of the proposed design was 40mm and 40mm, respectively as well as defected ground structure (DGS) in the ground and microstrip line feed used because of easy to feed and low spurious feed radiation with the simulated by using the CST software. The actual values of moisture content will be obtained by using standard oven drying method and measured by the vector network analyzer. (C) 2018 Elsevier Ltd. All rights reserved.
