摘　　要：文章采用MMANA-GAL软件仿真分析了一种新型半环(弓型)天线。给出了设计尺寸和几个典型频率下的辐射方向图,并比较了天线顶端连接方式的不同带来的影响。结果显示该天线实现了天波高仰角入射,在采用特殊调谐方式后能够克服短波通信的"通信盲区"问题。MMANA-GAL was adopted to simulate and analyze a new half-loop antenna. The results provide design size, several typical radiation patterns, and comparsion of the effect of the differences between top connection of the antenna. Results shows that the antenna achieves the high-elevation angle radiation when using sky-wave transmission. With special tuning method, the problem of HF communication gray zones can be solved.
