Analysis of Micro-Strip Patch Sensor of Various Sizes and Parameters for Non-invasive Electrolyte Sensing

Abstract

Electrolyte imbalance is a major health issue that can go unnoticed due to the lack of frequent testing. Most prevalent electrolyte monitoring measures require direct blood testing which is invasive in nature. Invasive monitoring measures are not only painful but also time-consuming. So non-invasive electrolyte monitoring is slowly gaining popularity. In this paper, non-invasive micro-strip patch antennas of different sizes and parameters have been analyzed. Micro-strip patch antennas of five different sizes and five different parameters have been analyzed for their sensitivity, linearity, and accuracy for a frequency range of 0.01GHz to 0.2GHz. Seven different concentrations of NaCl have been used for this analysis. Various research papers have found that there is a correlation between changing concentrations of NaCl and reflection coefficient S11 and resonant frequency. From this analysis, it has been observed that changing antenna size causes changes in antenna characteristics.
