摘　　要：短波通信对广播、航空业务、水上业务都有着重要的作用。短波通过电离层传输,传输过程不需要中继,通信终端又比较简单,使得短波在应急通信中发挥着举足轻重的作用。特别是在抗震救灾等领域,短波通信具有先天的优势。由于短波通过电离层传输,电离层又是一种随变信道,短波传输过程中会存在盲区现象,导致短波通信在短距离通信中效果不好,给短波通信在短距离传输时带来了比较大的瓶颈。文章提供了一种适用于短波短距离通信的天线选型,并对其实际通信性能进行了测试分析,为改善短波近距离通信质量提供了一种解决方案。HF communication plays an important role in broadcasting,aviation and maritime service.HF communication is transmitted through the ionosphere.The transmission channel does not need communication relay,and the communication terminal is relatively simple and portable.HF plays an important role in emergency communication,especially in earthquake relief,emergency communication and other fields,HF communication has inherent advantages.Since HF communication is transmitted through the ionosphere,and the ionosphere is a random channel,there would be blind area in the HF transmission,resulting in poor effect of HF communication in short distance communication,and a relatively large bottleneck for HF communication in short distance.This paper provides an antenna suitable for HF short distance communication,tests and analyzes its actual communication performance,providing a solution for HF short distance communication.
