Material Science
Agricultural Sensing Technology

Background:

Accurate measurement of dielectric properties is crucial for material characterization.
Soil water content (SWC) monitoring is vital for precision agriculture and environmental studies.
Existing methods for dielectric characterization and SWC determination can be complex or limited in scope.

Purpose of the Study:

To propose and validate a new, compact sensor for characterizing relative permittivity of dielectric materials.
To enable the determination of soil water content (SWC) using the developed sensor.
To demonstrate the sensor's effectiveness for various dielectric materials and soil types.

Main Methods:

Design and simulation of a complementary split-ring resonator (CSRR) based sensor integrated with a microstrip patch antenna.
Utilizing a 3D-printed container for holding the material under test (MUT).
Analysis based on the shift in antenna resonant frequencies correlated with changes in MUT's relative permittivity.
Fabrication of prototypes and experimental validation with dielectric materials and soil samples.

Main Results:

The sensor effectively characterizes the relative permittivity of various dielectric materials.
A strong correlation was established between resonant frequency shifts and MUT permittivity.
The sensor accurately determined soil water content in quartz sand and red clay samples.
Experimental results validated the sensor's performance against simulations and existing methods.

Conclusions:

The proposed CSRR-based sensor is a compact and effective tool for dielectric material characterization.
The sensor provides a reliable method for determining soil water content, with potential applications in agriculture.
The developed empirical model aids in the analysis and application of the sensor.
