摘　　要：文章采用MMANA-GAL软件仿真分析了车载三环天线的性能参数,给出了天线结构模型和几个频点下的方向图和增益值以及输入阻抗,结果显示该天线在低频端(5 MHz以下)工作时,近垂直(高仰角)辐射不好,大于5 MHz后天波高仰角入射增强,更利于克服短波通信盲区,天线的增益随着频率增大明显增大,三环结构加载有利于改善天线低频端阻抗特性。The software MMANA-GAL was adopted to simulate and analyze the vehicle mounted three-loop antenna. The paper presented the antenna＇s design size, radiation patterns, gain and input impandance in several typical frequency. Results shows that the antenna achieves the high-elevation angle radiation when the frequency value is bigger than 5 MHz, which can overcome the communication ＂blind zone＂. The frequency is bigger, and the antenna＇s gain is much bigger.
