In this paper, we present a design scheme of a wideband power divider structure with excellent flexibility and high isolation. The structure consists of a gradual transition from H-shaped spoof surface plasmon polaritons (SSPPs) transmission line (TL) to a pair of U-shaped SSPPs TLs on the ultrathin Polyimide substrate. A piece of graphene flake is loaded between the two U-shaped SSPPs TLs as an isolation resistive film. We experimentally demonstrate that the flexible broadband power divider can achieve equal power dividing with limited loss, good matching and high isolation covering 6.8-11.2 GHz under the flat, severely bent and twisted conditions.
