A passive microwave substrate‐integrated waveguide (SIW) resonator humidity sensor using black phosphorus (BP) as sensitive layers has been presented. The proposed structure consists of an SIW cavity resonator operating at S‐band and a folded sensing slot opened on the top plane. The humidity sensing performances of the proposed sensor were tested in the relative humidity range of 11–97%. Compared with an SIW resonator without BP sensitive layers, the sensitivity of the proposed SIW sensor with BP nanosheets significantly increased about 40 times.
