摘要

摘要

En 中文
本文提出了一种由三维基板集成波导（SIW）功分器馈电的4×4平面螺旋天线（PHA）阵列。4×4阵列由四个1×4 PHA子阵列组成，每个子阵列由SIW功分器馈电。由于螺旋天线为端射式，无法在二维平面内集成到4×4阵列中。为了实现4×4阵列，设计了一种SIW扭转垂直过渡结构以连接子阵列与SIW功分器。最终，所提出的4×4螺旋天线阵列被实现并制造以进行测量。PHA的中心频率为11 GHz，阻抗带宽（IBW）为10.16–11.99 GHz（16.64%），轴比带宽（ARBW）为10.53–11.47 GHz，峰值增益为18.44 dBi。仿真与测量结果吻合良好，验证了所提出设计的有效性。
