Design of microstrip antennas for glucometer application

In this paper, Low profile microstrip antennas for glucometer application are proposed. As dielectric constant of the material as a superstrate placed above 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 2015.01 for an operating frequency as low as 1 GHz. The operating frequency of antenna should be low as the low frequency microwave signal penetrate deep into tissues and have potential for practical application because of low physical area, low cost and better frequency resolution. Further, a high frequency resolution i.e. for a small change in glucose concentration leads to considerable shift in operating frequency, is achieved. The proposed microstrip antennas are designed and tested with aqueous glucose superstrate. This is advancement towards developing microstrip sensor for non-invasive glucometer application.
