A novel Antenna design for Non-Invasive Blood Glucose Measurement and its Sensitivity Optimization using ANN

A circular complementary split ring resonator loaded on symmetrical C-shaped slot patch antenna is simulated and fabricated for non-invasive blood glucose measurement. The proposed antenna has a compact dimension of (36×36×1.57) mm
³
. It has realized gain of about 9.5 dBi at 27.76 GHz resonant frequency. Further, artificial neural network method is used for optimization of sensitivity of antenna towards the change in relative permittivity of water-glucose solution. In this paper, an optimized antenna and water-glucose solution model is simulated in HFSS tool. The shift in frequency of 1.8 GHz with respect to the variation of the relative permittivity is achieved using proposed antenna.
