Abstract

The invention discloses a graphene-based ultra-low-profile lightweight bucket integrated ultra-wideband antenna, and the antenna comprises a system floor which comprises a bottom plate and a frame which is arranged at the periphery of the bottom plate and wraps the whole antenna; the isolation metal is located in the system floor, is parallel to the short frame of the system floor and coincides with the perpendicular bisector of the long frame of the system floor, and two ends are connected with the long frame of the system floor; the wave-absorbing material is positioned in the system floor and is symmetrically distributed by taking the isolation metal as an axis; the dielectric substrate is positioned above the wave-absorbing material, is symmetrically distributed by taking the isolation metal as an axis, and is the same as the wave-absorbing material in length and width; and the patch dipole antennas are located above the dielectric substrate and symmetrically distributed with the isolation metal as the axis, the working frequency bands of the two patch dipole antennas range from 0.3 GH to 4 GHz, and 30 dB isolation exists between the two patch dipole antennas. The invention has the advantages of light weight, stability, strong adaptability and higher detection performance.
