▎ 摘　　要

NOVELTY - The antenna comprises a polyimide substrate (6) whose lower end is provided with a micro-strip power distributor (1). A quarter-wavelength impedance converter (2) is located in a middle unit of the polyimide substrate and connected with the micro-strip power distributor. An upper unit of the quarter-wavelength impedance converter is connected with a micro-strip feeding balun (3). An upper unit of a cut metal ground (9) is carved with a groove line (7) and a rectangular groove (8). An upper end of the groove line on the cut metal ground is connected with a printed dipole antenna unit (10). The graphene sheet (5) is loaded on equivalent capacitance. USE - Graphene sheet based beam-scanning printed dipole flexible antenna. ADVANTAGE - Antenna utilizes external bias voltage to control conductivity characteristic of graphene so as to adjust capacitance of an equivalent capacitor branch, thus realizing change of a feeding phase of a printed dipole antenna unit, and hence adjusting phase difference between two unit printed dipole antenna units. The antenna has better application prospect. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene sheet based beam-scanning printed dipole flexible antenna.
