摘 要: 传统垂直巴伦长度较长,对小型化集成造成了不便。这里提出一种集成平行平面馈电结构的螺旋天线。所采用的天线与等角螺旋天线相比,尺寸更小且低频轴比明显优化。在设计中,将传统的垂直巴伦放置在天线同一平面,天线和巴伦被整合成一个双层结构。研究结果显示,新型螺旋天线保持了传统螺旋天线的典型辐射特性,垂直巴伦被整合到了同一平面,减小了天线垂直尺寸,从而达到减小天线整体尺寸的目的。

Abstract: The vertical Balun always has a significantly long length, inconsistent with the requirements of the low profile spiral antenna geometry. A spiral antenna with integrated parallel-plane feeding structure is proposed in this paper. The antenna used has smaller size and obviously improved axial ratio compared to the equiangular spiral antenna at low frequencies. And the traditional Balun in the third dimension is moved to the planar plane. The antenna and the Dyson-style Balun have been integrated into a multi-layer structure. The resulting structure maintains the typical radiation behavior and the broadband operation of the spiral antennas, but the vertical Balun is integrated at the same plane with the antenna. The overall size of the spiral antenna is largely reduced.
Key words: radio propagation; spiral antenna; parallel-plane feeding; ultra-wideband
