Single Fold Microstrip Ring Resonator Antenna for Glucometer
Abstract
Blood glucose measurement is vital for diabetes management. Blood glucose measurement technologies are both painful and costly. A microwave sensor can be useful for noninvasive determination of blood glucose levels. As a step towards developing a microwave based non-invasive blood glucose measurement technique, a microwave antenna or sensors are designed and tested with aqueous glucose. In this paper, a single fold microstrip ring resonator with compact structure is designed for use as a glucometer. As the dielectric constant of the superstrate material placed above ring resonator antenna changes, resonant characteristic of antenna varies and shift in the frequency is observed. The proposed microstrip antenna resonators are designed using Advanced Design System. As low frequency microwave signal penetrates deep into tissues and has potential for practical applications, a low profile low cost microstrip ring resonator antenna is proposed for better frequency resolution. A high frequency resolution is desired for glucometer i.e. for a small change in glucose concentration there should be a large frequency shift. The proposed ring resonator gives 10-20 MHz shift in frequency for every 10% change in glucose concentration.
