摘要：

在存在单元互耦的情况下，提出了锥台共形天线阵方向图的分析与综合方法．采用渐变缝隙天线作为阵列单元，先算出天线单元的阵中耦合方向图，然后以叠加原理为基础分析计算天线阵列的主极化和交叉极化方向图．采用Ansoft HFSS仿真软件对该锥台共形天线阵进行了仿真分析，结果表明，所提出的分析方法准确可靠，为锥台共形天线阵特性优化设计提供了方法支持．同时，采用雁群优化算法，对0°方位面内的阵列主极化扫描方向图及交叉极化方向图进行了优化综合．

关键词: 共形天线阵, 耦合方向图, 阵列分析, 雁群优化算法, 优化综合

Abstract:

The radiation pattern of the conformal antennas array is analyzed and synthesized by considering the effects of mutual coupling. First, we choose the tapered slot antenna as the element of the conformal array and calculate the patterns of the element in the environments of the array, and then analyze the array patterns of co-polarization and cross-polarization in terms of the combination of the element patterns. A comparison between the result of full-wave calculation by Ansoft HFSS for the whole array and that by this method is given to show the effectiveness of this method. In the meantime, geese particle swarm optimization (GPSO) is applied for the optimization of the scan patterns of co-polarization and the performance of the cross-polarization in the plane of φ=0°.

Key words: conformal array, mutual coupling pattern, array analysis, geese particle swarm optimization (GPSO), array pattern synthesis
