摘要 针对线天线自动设计中运算时间过长问题,提出了一种基于主从模型的并行森林竞争算法优化模型.主进程执行森林动态演化的竞争模型,从进程并行地执行自然树生长竞争模型并调用天线数值计算程序完成费时的阳光适应度计算.利用该算法设计出了一种端射高增益新型树结构线天线.其具有5个枝条,增益达到9.048 dBi,带宽为8.45%,在"元谋Ⅳ"Beowulf集群10个节点的并行效率达到了91%,从而验证了该算法的合理性和有效性. Aiming at the long runtime in automated design of tree-shaped line antenna,Parallelization of Forest Competition Algorithm is presented based on Master-Slave optimizing prototype.Master process performs the competition model of forest dynamical evolution.Slave process performs the growth-competition model of natural tree in parallel,and complets time-consuming sunlight fitness calculation.A novel tree-shaped line antenna is designed with end-fire and high gain.It has 5 branches,gain of 9.048dBi,and bandwidth of 8.45%.And its parallel efficiency reaches to 91% in 'Yuanmou-IV' Beowulf cluster system of 10 nodes,which validates the parallelized algorithm.
