| 摘 要： | 分析了天线单元之间的耦合作用后,运用理论推导得到了天线的散射矩阵.通过遗传算法对线阵天线进行了波束展宽,对阵列进行了互耦分析.分析结果表明:波瓣展宽后天线的旁瓣电平与增益都受到了互耦的影响,主要是由于相位加权破坏相位分布的连续性,导致了能量的利用效率降低,从而导致了天线的增益降低.在波束赋形中,可以加入算法强制相邻通道间的相位分布连续,之后得到的方向图可以适用阵列存在强耦合的情况.

| Abstract: | After analysing the coupling between antenna elements, using theoretical scattering matrix by the antenna.Based on genetic algorithm for linear array antenna beam broadening, analysis of the mutual coupling of array.Results show that: the lobe broadened antenna sidelobe level and gain mutual coupling that has affected, mainly due to the phase-weighted destroy phase continuity, resulting in low efficiency of energy use, which leads to reduced antenna gain.Shaped-beam, you can join algorithm for continuous phase distribution of forces between adjacent channels, after the applicable array of strong coupling. |
