▎ 摘　　要

NOVELTY - The antenna has a graphene floor provided with a graphite annular loop load radiation patch (2). A coaxial connector (5) is located on a graphene annular loop loading patch (2-4) that is connected with the graphite annular loop load radiation patch. A sector loading patch (2-5) is connected with an interdigitated capacitor structure. The graphite annular loop load radiation patch is provided with an annular loop (2-1) and a fan-shaped patch (2-2). The graphene annular loop loading patch is inserted into a central circular-shaped slotted patch (2-6). The graphite annular loop load radiation patch is connected with the coaxial joint. USE - Graphene-based annular loop fan-shaped loading patch based implantable circular polarized antenna. ADVANTAGE - The antenna can improve performance so as to effectively reduce energy consumption and improve transmission efficiency, and effectively reduces design size between four fan-shaped loading patches so as to increase rectangular size to form an interdigitated capacitor structure, thus reducing resonant frequency. The antenna obtains circular polarization characteristics, and has wide frequency band, better anti-interference effect, better biological compatibility, and can satisfy working requirement in complex environment.
