Abstract: Microwave propagation inside a waveguide is known to be dependent on dielectric filled inside the guide. The soil can be thought of as dielectric material and filled in the rectangular waveguide to modify wave propagation. This paper describes different approach of detection of water mixed in the soil using C-band microwave waveguide, after filling dirty soil inside it. The results of detection parameter from 5 to 6 GHz have been shown in agreement with the expected and % of water content in the soil can be known using such approach, which may be extended for applications on future planetary missions.
