| 摘 要： | 谐振式四臂螺旋天线由于不需要参考地、能产生赋形方向图且重量轻、尺寸小,在空间通信中得到广泛的应用.本文从低轨道小卫星通信系统的要求出发,设计了两种实际的谐振式四臂螺旋天线,天线采用了新颖的90°自相移结构及平衡馈电结构.最后采用有限元方法对其辐射特性进行分析,计算结果与测试数据的一致性好.

| Abstract: | The resonant quadrifilar helix antennas have been widely applied to space communication links because of its relatively small volume and light weight plus its capability of providing shaped-conical beam,end-fire radiation without requiring a ground plane.The paper designs two actual resonant quadrifilar helix antennas with a novel 90°self-phased feed structure and a special infinite balun.The actual antennas are simulated by the finite element method.The simulation resultwell fits the measured data. |
