Return Loss of Diabetic Persons

Microwave active antenna sensor based MDBM meter is developed for continuous glucose measurement in human body. MDBM meter consists of Antiallergic Abdominal belt with radar IC (RCWL0516) mixer IC (BFR520) and HSIS antenna sensor. Microwave active antenna sensor is H-shaped patch with I-shaped slot, which is placed on human pancreas and acquires reflected microwave signals from dielectric materials in pancreas. Pancreas dielectric materials radiation property changes during insulin secretion. In MDBM meter, antenna receives reflected signals from dielectric minerals in pancreas through HSIS active sensor antenna process with microcontroller and predicts diabetic value based on machine learning. Return loss of HSIS antenna sensor is highly correlated with laboratory based diabetic measurement.
