| 摘 要： | 基于改进型Vivaldi天线单元,采用4单元十字交叉组合构成圆极化天线,并通过增加耦合金属立柱改善天线轴比,设计了一种超宽频宽角覆盖圆极化直线阵。该天线在1.25-4.1 GHz频段电压驻波比(VSWR)小于2,在1.6-3.6 GHz频段轴比小于3 dB,在垂直扫描方向具备宽角覆盖能力,具备较高的工程应用价值。

| Abstract: | Based on improved Vivaldi antenna unit, using four crossed units constitutes a circularly polarized antenna, further improving axial ratio （AR） by adding the coupling metal columns, an ultra-broadband wide-angle circularly polarized linear antenna array is designed. The voltage standing wave ratio （VSWR） of the antenna is less than 2 at the frequency range of 1.25 to 4.1 GHz. Meanwhile, the AR is less than 3 dB at the frequency range of 1.6 to 3.6 GHz. This antenna has very wide angle coverage ability, and has high engineering value. |
