GRAPHENE-BASED COUPLER WITH ADJUSTABLE POWER DISTRIBUTION RATIO

WIPO Patent Application WO/2019/029127

A1

The present utility model provides a graphene-based coupler with an adjustable power distribution ratio, comprising a dielectric slab, a resonant ring, and a metal patch; the resonant ring comprises a U-shaped upper portion and a U-shaped bottom with openings arranged oppositely; the U-shaped upper portion and the U-shaped bottom are connected by means of a first rectangular portion and a second rectangular portion; first graphene patches are respectively attached to the inner walls of the U-shaped upper portion and the U-shaped bottom; second graphene patches are respectively attached to the inner walls of the first and second rectangular portions; a first metal strip is respectively connected to either side of the open end of each of the U-shaped upper portion and the U-shaped bottom; a pair of second metal strips are symmetrically arranged on the upper and lower sides of each of the first metal strips; the outer ends of each pair of second metal strips are both connected to a rectangular metal sheet to form four ports; the vertical central axis of the U-shaped upper portion superposes that of the U-shaped bottom; the first and second rectangular portions are symmetric about the central axis. The present utility model can implement dynamic adjustment of the power distribution ratio of a coupler.
