Design and simulate an antenna for aqueous glucose measurement

Abstract

Diabetes is a disease that afflicts millions of people. Blood glucose measurement is a vital task to manage diabetes. The available technologies for blood glucose measurement are both painful and costly. A microwave sensor can be used for the non-invasive determination of blood glucose levels. As the step towards developing a non-invasive blood glucose measurement based on microwave, a sensor is designed and tested with aqueous glucose. A Sonnet Microwave Simulation Studio Suite v 13.52 is used for the design and simulation of sensor. Three types of sensor namely ring resonator, a microwave single spiral ring resonator and double spiral resonator are designed and simulated. The simulation result shows that, the resonant response of the sensor changes as per the change in permittivity of aqueous glucose and single spiral ring resonator exhibits excellent response as it gives maximum measurable frequency shift.
