低副瓣智能天线阵型研究

内容简介：由于智能天线所处电磁环境的特殊性，实现低副瓣特性及快速波束赋形尤其重要。本文从阵型角度出发，计算了圆阵中心阵元、圆阵层数及阵元密度分布对于降低副瓣的作用，并分析了球面阵列的辐射特性；所得结论可供智能天线的阵型设计参考。

Abstract：Due to the speciality of electromagnetic environment for smart antenna, low sidelobe and high-speed beam-forming are two key problems. Focusing on the geometry of smart antenna, the effects of center element and the ring number of circular array on side-lobe are calculated and analyzied; the spatial symmetry of array factor for spherical surface array is discussed also. The conclusion derived can be used as a reference for the geometry design of smart antenna.
