▎ 摘　　要

NOVELTY - The graphene-based flexible broadband monopole wearable antenna has a radiation unit fixed on a flexible medium substrate. A co-ground structure is located above the radiation unit through a feed network. The radiation unit is provided with a feeding guide belt, a first transition connecting unit, a rectangular groove antenna unit, a second transition connecting unit and a U-shaped groove antenna unit. The U-shaped groove antenna unit is provided with a first antenna unit and a second antenna unit. The second antenna unit is formed with a U-shaped groove. A rectangular bump is located in the U-shaped groove. USE - Graphene-based flexible broadband monopole wearable antenna. ADVANTAGE - Graphene-based flexible broadband monopole wearable antenna is provided with the rectangular groove and the U-shaped groove, so as to prolong current path, increase antenna electric length and realize broadband and miniaturization of the antenna. The co-ground structure broadens working bandwidth of the wearable antenna so as to widen application prospect of the wearable antenna. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of graphene-based flexible broadband monopole wearable antenna.
