设计了一种工作频带范围为22-30GHz的圆锥波纹喇叭。通过电磁场仿真软件HFSS对该天线进行仿真,计算了天线的驻波系数、交叉极化、增益方向图、相位中心等参数。计算结果表明,该波纹喇叭方向图对称性好、交叉极化低,可用作高性能反射面天线馈源。 A conic corrugated horn with a working frequency range of 22-30GHz is designed. The electromagnetic field simulation software HFSS was used to simulate the antenna, and the parameters such as standing wave coefficient, cross polarization, gain pattern and phase center were calculated. The calculation results show that the corrugated horn has good symmetry and low cross-polarization, and can be used as the feed of high-performance reflector antenna.
