摘　　要：本文主要对谐振式四臂螺旋天线的基本理论进行研究,并设计了一个宽带宽波束左旋圆极化四臂螺旋天线。采用带隔离电阻的威尔金森功分器对四个螺旋臂进行馈电,实现要求的相位关系,仿真结果表明该天线具有良好的电气性能。The basic theory of resonant quadrifilar helical antenna is mainly analyzed,and a broad-band and wide-beam left hand circular polarization(LHCP)quadrifilar helical antenna is designed.A Wilkinson power divider with isolation resistances is used to feed 4 spiral arms and achieve required phase relationship.The simulation results show that the antenna has favorable electrical performance.
