【摘要】 主要研究了均匀N元直线阵阵因子数学模型和三个参数,应用MATLAB对边射直线阵、端射直线阵、波束调向直线阵的性能进行了仿真分析.通过仿真分析比较,得出适当地变更单元天线的数目、间距及电流相位可以改变直线阵的方向性和主瓣宽度的结论,从而为智能天线的研究提供理论基础.更多还原

【Abstract】 This article mainly studies on array factor math mode of homogeneous N element linear array and three parameters,making a performance stimulation analysis on broadside array,end-fire array and beam switched linear array by MATLAB.Through the simulation,analysis and compare,we can make a conclusion that by the means of properly changing the unit antenna number,space and current phase,the linear directivity and chief lobes width will be changed,which providing a theoretical foundation for the research of Smart Antenna Engineering.更多还原
