Microwave signals have gained significant interest for emerging medical applications. An example includes blood glucose monitoring where the complex scenario can compromise an accurate sensing, due to a number of factors, such as system noise, environmental temperature, and all those factors affecting the dielectric properties of tissues (e.g., variation across people). In order to mitigate such a drawback, a modified patch resonator (2.3 GHz) with a solid "matching layer"interposed between a traditional microstrip antenna and the phantom under test, is presented. Numerical results confirm this solution allows to achieve a good trade-off between measurement stability and sensitivity, allowing to discriminate glucose concentrations in a broad range from 100 up to 350 mg/dL.

Abstract
Microwave signals have gained significant interest for emerging medical applications. An example includes blood glucose monitoring where the complex scenario can compromise an accurate sensing, due to a number of factors, such as system noise, environmental temperature, and all those factors affecting the dielectric properties of tissues (e.g., variation across people). In order to mitigate such a drawback, a modified patch resonator (2.3 GHz) with a solid "matching layer"interposed between a traditional microstrip antenna and the phantom under test, is presented. Numerical results confirm this solution allows to achieve a good trade-off between measurement stability and sensitivity, allowing to discriminate glucose concentrations in a broad range from 100 up to 350 mg/dL.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
