The Design of Microwave Cavity Resonator Used for Measuring the Moisture Content in Plant Leaves

Abstract:

This paper designs the cavity parameters of rectangular microwave cavity resonator, mainly including the design of cavity size, coupled diaphragm radius, and the position to place leaf, to make the largest power of resonant cavity and most significant impact on S11 parameters when the dielectric constant changes. Then conducts optimized analysis with finite element analysis software HFSS, gains the relation between dielectric constant and resonator parameters within the 3.2GHz-3.8GHz swept frequency range, and analyzes the simulation results. Finally, concludes the application sphere of cavity resonator designed in this paper according to the multiformity of plant leaves measured, and makes a simple introduction to the improvement methods.
