摘　　要：研究了一种20GHz和30GHz双频六角形阵列天线方向图的综合方法。采用了非线性最小二乘法对影响天线方向图的诸多参数,如单元的幅度和相位、单元间距以及单元在阵中的位置进行了优化设计,以使双频阵列方向图在最小二乘意义上逼近预先给定的理想方向图。仿真结果表明该方法可行、有效。The optimal design of a dual frequency hexagonal array antenna operated at 20GHz and 30GHz is addressed in this paper. The nonlinear least-square method is employed to optimize the parameters affecting antenna pattern such as amplitude and phase of elements, the spaces between elements, as well as the positions of element in array, so that the pattern of dual frequency array antenna approaches the desired pattern in least square sense. Simulation results show the proposed method is feasible and efficient.
