A Novel Cesaro Fractal EBG-Based Sensing Platform for Dielectric Characterization of Liquids

This article presents a compact, cost-effective, and contactless fractal modified electromagnetic bandgap structure (EBG)-based microwave sensing platform for dielectric characterization of liquids by analyzing the variation in reflection coefficient an antenna. The reported design is composed triangular-shaped antenna ( 0.323? o ×0.323? ) placed over 3 ×3 array Cesaro fractal-based EBG plane 0.67? ×0.67? operating at 2.45 GHz. A significant enhancement E-field region has been achieved with incorporation fractals which results increased sensitivity compactness. To validate its performance, absolute solutions butan-1-ol, methanol, water are loaded, maximum measured 0.875% quality factor 90.05 achieved. Moreover, rms error retrieved values constant loss tangent liquid under test found to be 1.092% 0.813%, respectively. Our demonstrated EBG-based sensor compact footprint good precision, affordability, ease operation detecting applications.
