dc.description.abstractAbstract: In this paper, a graphene oxide (GO) coated substrate material is electrically characterized. The permittivity, loss tangent, permeability, and resistance are measured. A planar antenna with slots is designed on an RT/Duroid 5880 substrate. A thin layer of graphene oxide is coated on the identical slots of the planar antenna. The GO-assisted antenna sensor resonates at 2.51 GHz frequency. The graphene oxide-based antenna sensor performs contact-free sensing of relative humidity. The frequency sensitivity is approximately 17.5 MHz/10%RH. The design sensor gives a 93.50% linearity. The limit of detection is 30.55 RH%. Graphic Abstract: (Figure presented.) © The Korean Institute of Electrical and Electronic Material Engineers 2024.
