A Tunable Wilkinson Power Divider Based on Graphene

In this paper, a tunable Wilkinson power divider based on graphene is proposed. By adding four graphene stubs to the power divider to change the output power, different power division ratios can be achieved. The power divider at a center frequency of 3GHz provides power division ratios of 1:6, 6:1, 3:1 and $1: 3$.
