description The invention discloses a terahertz detector based on a graphene composite structure beam scanning antenna, which belongs to the field of terahertz detectors and comprises a source electrode, a grid electrode, a drain electrode, a grid electrode dielectric layer, the graphene composite structure beam scanning antenna and a direct current bias voltage system. The graphene composite structure beam scanning antenna comprises a substrate and two graphene layers arranged in parallel. The direct-current bias voltage system comprises a polycrystalline silicon direct-current bias voltage plate and direct-current voltage and is used for providing adjustable direct-current voltage for the two graphene layers at the same time and regulating and controlling the chemical potential of the graphene, so that the surface conductivity of the graphene is changed, and the working frequency band and the absorption direction of the antenna are adjusted. According to the invention, ultra-wideband, high-sensitivity and large-range t
