A passive sensing continuous glucose monitoring system and method of use thereof. The system includes a passive antenna formed of biocompatible silicon carbide (SiC), modeled to a desired frequency, which is permanently implanted subcutaneously. The system further includes an external-to-the-body transmitting antenna to detect changes in the blood glucose level by sending a radio signal at the frequency of the implanted passive antenna into the body. This signal is received and reflected by the passive antenna, and the reflected signal is then received at an external-to-the-body receiving antenna. Changes in the glucose level lead to modifications in the signal and can be used to determine the blood glucose level externally.
