摘　　要：本文设计了1种双圆极化天线,由波导同轴转化器,圆极化器和喇叭体3部分组成。波导同轴转化器使用同轴-双脊-矩形波导过渡结构,实现阻抗匹配和模式转化。圆极化器使用阶级隔板形式,实现线极化波与双圆极化波的相互转换。多模喇叭体用于实现高增益。仿真结果表明该天线具有增益高、带宽宽、轴比性能好等优点。In this paper,a dual circularly polarized antenna is designed,which consists of a coaxial-waveguide converter,a waveguide circular polarizer and a horn.In particular,the coaxial-ridge waveguide-rectangular waveguide is used to realize impedance matching and mode conversion of electromagnetic microwave.The circular polarizer with a multistage diaphragm is designed to realize the mode conversion between linear polarization wave and double circular polarization wave.The multi-mode horn is also used to improve gain.The simulation results show that the proposed antenna has the advantages of high gain,wide bandwidth and good axial ratio.
