A split-ring resonator-based microwave sensor comprises a metallic ring with a slit and integrated monopole patch antennas on top of a dielectric substrate. The resonant frequency of the device is measured as 2.12 GHz. The device is demonstrated as a resonant biomolecular sensor where the interactions between heparin and fibroblast growth factor 2 are probed. The sensitivity of the device is obtained as 3.7 kHz/(ng/ml) with respect to changes in concentration of heparin.
