▎ 摘  要

NOVELTY - Graphene circularly polarized wear-resistant antenna based on an artificial magnetic conductor array comprises a circularly polarized radiation unit (1), second flexible medium supporting layer (2) and an artificial magnetic conductor array reflecting plate (3 stacked sequentially from top to bottom. The circularly polarized radiation unit comprises first medium flexible substrate (11) of a square shape, and a feeding floor (12) printed on the graphene surface of the substrate. The gap inside is printed with L-type radiation patch (13). The opening is printed with a rectangular coplanar waveguide feed line (14) with longitudinal arm connecting the L-type radiation patch. Second flexible medium support layer is made of a flexible medium material. The artificial magnetic conductor array reflecting plate is composed of an artificial magnetic conductor unit (31) arranged periodically. The artificial magnetic conductor unit comprises third medium flexible substrate (311). USE - Graphene circularly polarized wearable antenna based on an artificial magnetic conductor array. ADVANTAGE - The gain of the wearable antenna is effectively increased by reflecting the electromagnetic wave of the circularly polarized radiation unit back to the radiation to the main radiation direction of the radiation unit in the original phase when an incident wave irradiates the artificial magnetic conductor surface. The light weight and low specific absorption rate gain increasing the antenna is ensured.
