半球面螺旋天线的仿真设计

一种半球面螺旋天线的仿真设计

内容简介：利用Ansoft高频电磁仿真软件HFSS设计了一种新型的半球面螺旋天线,设计内容包括半球螺旋辐射器和馈电巴伦,给出了天线的驻波、增益、极化、轴比及方向图等随频率变化的曲线。计算与试验结果表明,在（1.8~6.0）GHz的频带内,天线的驻波比均小于2.5,轴比小于3 dB,增益小于4 dB。

Abstract：A new hemispherical spiral antenna is designed and simulated with Ansoft HFSS,which includes hemispherical spiral radiator and feed balun.The curves of the VSWR,gain,polarization,axial ratio and pattern vs.Frequency are presented,respectively.The calculated and test results show that within the range of（1.8~6.0） GHz,VSWR is less than 2.5,that AR is less than 3 dB,and that the gain is less than 4 dB.
