| 研究了20GHz和30GHz双频段圆环阵列天线的方向图综合方法。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优化设计，以使双频段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。 |

| () |
| Abstract: |
| The optimal design of the dual frequency circular array antenna at 20GHz and 30GHz is addressed in this paper. The nonlinear least - square method is adopted to optimize the parameters affecting antenna pattern such as the amplitude and phase of the elements, the space between the elements as well as the positions of the elements in array, such that the pattern of dual frequency array antenna approaches the desired pattern in the least square sense. Simulation results show the proposed method is feasible and efficient. |
