“…For example, dielectric spectroscopy was used in [5] to measure blood plasma in the range 0.5-20 GHz, and resonant cavity setups have been employed in [6,7] operating between 2 and 3 GHz. Frequency ranges between 1.0-2.5 GHz [8] and 5.0-8.5 GHz [9] have also been used in configurations with antenna sensors. Higher microwave frequencies have been proposed in [10][11][12], but in a different context than in the present work.…”

The paper presents the first in vivo glucose monitoring animal study in a pig, which correlates radio frequency signal transmission changes with changes in blood glucose concentration in the 58-62 GHz frequency range. The presented non-invasive glucose sensing system consists of two opposite facing patch antennas sandwiching glucose-loaded samples. Prior to the animal study, the system was tested using saline solution samples, for which a linear relationship between changes in transmitted signal and glucose concentration was observed. In the animal study, glucose concentration changes were induced by injecting a known glucose solution in the blood stream. The non-invasive transmission measurements were compared to the glucose levels obtained invasively from the animal. Our results suggest that the system can detect spikes in glucose concentration in the blood, which is an important milestone towards non-invasive glucose monitoring.

“…Among the various candidate technologies, the use of electromagnetic (EM) waves (e.g. optical methods studied in [10][11][12]) and particularly microwaves has shown promise in detecting changes in the electrical properties of blood plasma as a function of glucose concentration [4,6,7,[13][14][15][16][17][18][19][20]. These results have motivated the present study towards the development of a non-invasive glucose monitoring system using the 50 -75 GHz mm-wave band.…”

Microwave imaging is recognized as a potential candidate for biomedical applications, such as breast cancer detection. In this context a miniature antenna is used for quantitative imaging of inhomogeneous tissues. Microwave breast imaging (MBI) uses low power and longer wavelength signals to obtain information about breast tissues, and promises a safer and more accurate modality for regular breast scanning. This paper presents a miniature microstrip antenna that can be placed in contact with the breast model to investigate the presence of malignant tissues. A miniature antenna has been designed, and placed toward a breast phantom model with inhomogeneous tissues. Images are successfully obtained by using scattering electromagnetic waves (S 11 ) from the designed model. The antenna was then manufactured and tested.
