To realize the miniaturization of directional MF antenna array, the modern electromagnetism (EM) simulation software, named as FEKO, is adopted to optimize conventional MF T-shape antenna (i. e. folded-T-shape antenna), which is taken as an antenna unit. Three T-shape antenna units are arrayed in an antenna unit. The miniaturization of directional MF antenna array is realized with feed technique of different amplitude or phase, which has a wide application prospect in engineering.%为了实现定向中波天线阵的小型化,采用现代专业电磁仿真软件FEKO,对常规的中波T型天线进行改进和优化设计使其达到小型化,并以此为天线单元,进行三单元组阵,采用不等幅、不同相馈电技术,从而实现定向中波天线阵的小型化设计,具有一定的工程应用前景.
