(CN207038682-U) NOVELTY - The utility model claims a graphene-based distribution ratio coupler with adjustable power, comprising a medium plate, a resonant ring and the metal patch, the resonant ring comprises an opening opposite to the U-shaped upper part and a U-shaped bottom. U-shaped bottom of the U-shaped upper part and connected by a first rectangular portion and a second rectangular portion; inner wall of the U-shaped upper part and U-shaped bottom is respectively adhered to the first graphene sheet, respectively adhered to inner wall of the first rectangle and the second rectangle part is set on the second graphene sheet; the two sides of the opening end of the U-shaped upper part and U-shaped bottom are respectively connected with a first metal strip, each of the upper and lower side of the first metal strip is symmetrically set with a pair of second metal strips, each forming four ports are connected to a rectangular metal sheet to the outer end of the second metal strip, the vertical central axis of the U-shaped upper part and a U-shaped bottom are overlapped, the first rectangle and the second rectangle part symmetrical about the central axis. This utility model can realize power distribution of coupler ratio can be dynamically adjusted. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene-based adjustable power distribution ratio coupler. Graphene-based adjustable power distribution ratio coupler (1) Resonant ring (11) Ports (12-15) U-shaped upper portion (111) U-shaped bottom portion (112) Rectangular portions (113, 114) Metal strips (117, 118)
