一种平面结构的宽带水平极化全向天线

内容简介：设计并加工了一种平面结构的宽带水平极化全向天线,该天线由四个改进的弯曲偶极子加上各自的耦合单元构成。天线在水平面内能很好地实现全向辐射特性,在4.8～6.8GHz的频带范围内,回波损耗小于-10dB,水平极化不圆度小于±0.7dB,交叉极化优于-20dB。

Abstract：A broadband omni-directional planar configuration antenna with horizontal polarization is designed and fabricated,which makes up of 4 improved curving dipole with their coupling elements.A good omni-directionality is achieved at horizontal plane,and the return loss is less than-10dB,the variations of energy in horizontal polarization far-field pattern are less than ±0.7dB,cross polarization superior than-20dB between the operating frequency rang 4.8～6.8GHz.
