Summary:We present a new type of adjustable graphenebased attenuator, which is manufactured on a half-mode substrate integrated waveguide. The presented attenuator is constituted by a graphene sandwich structure spread on a halfmode substrate integrated waveguide. The attenuation of this attenuator can be adjusted by adjusting the square resistance of graphene. From 8 GHz to 19 GHz, the attenuation can be adjusted from 3 dB to 15 dB.
