摘　　要：介绍了短波通信盲区产生的原因和解决途径;对短波车载半环天线及其变形鞭状天线的输入阻抗、最大辐射仰角、方向图、最大增益等参数进行了仿真分析,得出了半环天线用于NVIS通信的最佳工作频段;最后通过对通信频率、通信距离和通信效果的实测,有力地验证了车载半环天线的NVIS通信能力。The causes and solutions of blind area in HF communication are analyzed at first. The typical vehicle mounted half-loop antenna and its transformation called whip antenna are used for simulation to analyze the parameters such as impedance,maximum elevation angle,pattern and maximum gain with different frequencies.Then the optimum working frequency bands of half-loop antenna is obtained for NVIS communication. Finally,the NVIS communication abilities of vehicle mounted half-loop HF antenna are verified by actual measurements with frequencies,distances and effects of communication.
