摘要
构建直线阵列、圆阵列和平面阵列天线的数学模型并推导其阵因子表达式,借助Matlab对3种不同类型的阵列天线方向图进行仿真研究。对比阵元数、波长、阵元间距等参数对不同类型阵列天线方向图的影响,仿真结果表明:直线阵、平面阵的性能与阵元数、阵元间距呈正相关,与波长呈负相关;圆阵的性能与阵元数呈正相关,而与圆阵半径和波长的关系并不是线性的。
The mathematical models of linear arrays antenna,circular arrays and planar arrays are constructed,and the corresponding array factor expressions are derived.The simulation research on three kinds of array antenna directional diagrams are carried out with Matlab.Through a comparative study of the influence of the number of elements,wavelength,spacing and other parameters on the different types of array antenna directional diagrams,the simulation results show that the performance of linear array and plane array is positively correlated with the number of array elements and the spacing of array elements,and negatively correlated with the wavelength.The performance of circular array is positively correlated with the number of array elements,but not linearly correlated with the radius and wavelength of circular array.
