摘　　要：论文论述了圆锥对数螺旋天线及宽带馈电巴仑的设计方法,并利用ANSYS Electronics Desktop软件进行了仿真设计。天线的设计目标在1.2 GHz~2.5 GHz的频带内,驻波比≤2,轴比≤3 dB,垂直面具有半球形方向图。仿真结果表明,该天线具有良好的宽频带圆极化性能,辐射方向图在全频带内为半球形。根据仿真结果,加工了实物样机,实测结果与仿真结果吻合。A conical logarithmic spiral antenna with wideband feed Balun is presented in this paper,which is simulated with ANSYS Electronics Desktop software.The antenna is designed to have a standing wave ratio of ≤ 2,an axis ratio of ≤ 3 dB,and a hemispherical pattern in the vertical plane in the frequency band from 1.2 GHz to 2.5 GHz.The simulation results show that the antenna has good wideband circular polarization performance and the radiation pattern is hemispherical in the full frequency band.According to the simulation results,the prototype is machined,and the measured results are in agreement with the simulation results.
