【摘要】 智能天线作为通信领域中一项先进技术,最近得到了大力的发展,波束形成是智能天线技术的核心和理论基础,而阵列形式直接影响到天线的波束形成.通过对不同阵列形式的分析,研究了在相同阵元数情况下各种阵型的方向图.通过一定的准则搜索,对每种阵列得到了一个最优解并给出各种最优阵型的比较.最后通过性能比较得出,外环为奇数中心有一阵元的阵列形式为最优性能比较理想.更多还原

【Abstract】 Beam forming is the kernel of smart antenna,and provides fundamental theory,and the pattern of an antenna array is determined by the geometry of arrary .Different geometries of eightelement antenna array,and their optimization array were discusssed ,and a geometry of array with better performance was recommended.更多还原
